Send Message 1.0.0: one PIN, one place to send from; Slack 1.3.0 and ProdCom 1.4.0 become messaging providers

A new send-message module owns everything a dashboard sends: the PIN
(switchable off in admin), the unlock tokens, the Send message and Quick
replies tiles, the quick replies and quick emojis. It opens no upstream
connection of its own — it finds every module declaring
provides: ["messaging"] through the shell's module list and hands each
message to that module's POST /messaging/send over loopback, so Slack keeps
its one Slack connection and ProdCom its one ProdCom connection. Providers
check the browser's unlock token with GET /verify over loopback before
touching their upstream, so no browser on the network can post as the
location without having entered the PIN here.

Slack 1.3.0 is view-only plus reactions: the Sending group, PIN, send tiles
and quick replies are gone; it serves the messaging descriptor (channels as
recipients) and its reactions ride on the Send Message unlock. A layout's
old Send message / Quick replies tiles draw nothing until removed.

ProdCom 1.4.0 serves the descriptor as identities — only channels with
typingEnabled, since typed text goes out *as* a channel — and posts with
POST /api/v1/channels/{id}/send. Its tile is a click-to-target like Slack's
(accent stripe along the bottom), and typed entries carry a keyboard mark.

The tiles: click any Slack or ProdCom transcript to point sends there; a
Send as menu (only for platforms with identities, hidden otherwise) picks
the ProdCom channel to speak as; the choice is saved with the tile so named
layouts remember it. Wording follows the role — "Send message to #ops…" /
"Send message to ProdCom as FOH…". The PIN pad's dots ride on a real
numeric input so a phone's keyboard appears. Outcome is an icon beside
Send (check / blocked, five seconds, sentence as tooltip). A pill on the
box's bottom edge trades box height for rows of quick-emoji keys, a row
at a time; the single row scrolls sideways on a narrow tile with Send
pinned in place.

The module guide documents the provider contract and the page bus
(window.proddashMessaging + proddash:messaging:* events) the tiles share;
the ProdCom mock gained the send route.

+### Offering messaging to the Send Message module
+
+The Send Message module is the one place a dashboard sends from — a
+PIN-gated compose box and a grid of quick replies — whatever the platform.
+It owns nothing upstream: a module that *can* deliver a message (Slack posts
+to a channel, ProdCom puts typed text on a comms channel) offers that over
+its own routes, keeps its one upstream connection, and the Send Message
+module hands messages to it over loopback. A provider has no PIN, no send
+tile and no quick replies of its own; the shell's Add-tile picker shows the
+Send message and Quick replies tiles once, under Send Message.
+
+A module offers messaging by:
+
+1. Declaring it — `"provides": ["messaging"]` in `module.json`. The Send
+   Message module re-reads `/api/modules` every 30 s, so a provider installed
+   mid-session shows up without a restart.
+2. Serving `GET /messaging` — what it can send to, from state it already
+   holds (it is polled every few seconds while a send tile is open):
+
+```json
+{
+  "label": "Slack",
+  "identity": "Apollo Beach",
+  "destinationRole": "recipient",
+  "status": { "state": "ok", "message": "Apollo Beach · #production, #ops" },
+  "destinations": [
+    { "id": "C01ABC", "label": "#production" },
+    { "id": "C02DEF", "label": "#ops", "color": "#5c9de0" }
+  ],
+  "emptyMessage": "",
+  "maxChars": 4000
+}
+```
+
+| Field | Meaning |
+| --- | --- |
+| `label` | The platform's name, as the sending line and the Send as menu show it. |
+| `identity` | Who a message appears to come from when that is fixed by the connection, or `''`. Shown as "as Apollo Beach". |
+| `destinationRole` | What a destination *is*. `recipient` (the default): a message goes **to** it — a Slack channel — and the operator picks one by clicking its transcript tile, so it never appears in the Send as menu. `identity`: a message goes out **as** it — a ProdCom channel — and the Send as menu lists them; the tiles then say "Send message to ProdCom as FOH" and "Sent to ProdCom as FOH". The menu exists only while some installed platform offers identities. |
+| `status` | `ok`, `connecting` or `error` plus one line — the same thing your `health()` says. A provider in error is still listed, so the operator sees why a send will fail before trying. |
+| `destinations` | Where a message can go, or who it can go out as: a stable `id` (what `/messaging/send` receives), a `label`, and an optional `color`. Offer only what will work — ProdCom lists just the channels that accept typed text. Order is the order the menu shows. |
+| `emptyMessage` | Optional: why the list is empty, when you know ("No ProdCom channel accepts typed text — turn on typing for one in ProdCom"). The tiles show it in place of a destination. |
+| `maxChars` | The longest text you accept; the Send Message module refuses longer ones before asking you. |
+
+3. Serving `POST /messaging/send` — `{ "destination": "<id>", "text": "…" }`
+   with the browser's unlock token as `Authorization: Bearer …`. **Check the
+   token before touching your upstream**: the Send Message module owns the
+   PIN, so ask it — `GET http://127.0.0.1:${shell.port}/api/modules/send-message/verify`
+   with the same `Authorization` header answers `200 { ok: true, expiresAt }`
+   or `401`. A `404` means no Send Message module is installed or enabled:
+   refuse with a sentence that says so. Without this check, any browser on
+   the network could post as the location by calling your route directly.
+   Answer `200 { "ok": true, "label": "#ops" }` when it landed, otherwise
+   `{ "error": "<one sentence a tech can act on>", "code": "…" }` with `400`
+   (bad destination or text), `401` (the token was refused), `429` (your
+   upstream is rate-limiting) or `502` (your upstream failed). Validate the
+   destination against your own list — never pass an arbitrary id upstream.
+
+The same verification gates any other outbound action a module offers from
+its tiles — the Slack transcript's emoji reactions ride on it — so a module
+never needs a PIN of its own: one unlock serves every messaging tile on the
+page. The `slack` and `prodcom-transcript` modules are the reference
+implementations (`verifyUnlock()` in either server entry is the whole check).
+
+### Messaging on the page
+
+Where the next message goes is a fact about the whole dashboard, not one
+tile: the Send message tile, the Quick replies tile and every transcript on
+the page must agree, and they belong to different modules. Modules don't
+import each other, so the agreement lives on `window` — one plain object plus
+`CustomEvent`s on `window`, created by whichever messaging-aware tile mounts
+first:
+
+```js
+window.proddashMessaging = {
+  version: 1,
+  target: { provider: '', destination: '', providerLabel: '', destinationLabel: '', identity: '' },
+  unlock: { token: '', expiresAt: 0, reason: '' },
+  quickEmojis: [],            // the Send Message module's admin list, plain strings
+  transcripts: new Map(),     // instanceId → { provider, destination }
+  senders: new Set(),         // instanceIds of Send message / Quick replies tiles
+};
+```
+
+Events, all named `proddash:messaging:<name>` with the payload in `detail`:
+
+| Event | Who sends it | Meaning |
+| --- | --- | --- |
+| `select` | a transcript tile, or a Send as menu | `{ provider, destination }` — the operator pointed the senders here. A tile bound to one recipient (a Slack channel transcript) names it; one that shows a whole platform (ProdCom) sends `destination: ''` and the Send Message tile keeps the identity it has chosen for that platform. |
+| `target` | the Send Message tiles | `window.proddashMessaging.target` changed: where the next message goes, resolved. A transcript compares `provider` (and `destination`, when it has one) and lights its bottom edge. |
+| `unlock` | the Send Message tiles; a provider's tile on a `401` | `window.proddashMessaging.unlock` changed. Read the token from the object, never cache it; `''` means locked, with `reason` saying why. |
+| `transcripts` | transcript tiles | the `transcripts` map changed (a tile mounted, unmounted or learned its channel). Register once you know your destination; unregister in `stop()`. This is how a dashboard with one transcript sends there by default. |
+| `senders` | the Send Message tiles | the `senders` set changed — a transcript's locked note can say "add a Send message tile" rather than "enter the PIN". |
+
+A transcript tile needs only three things: emit `select` on a click in its
+body, register in `transcripts`, and toggle a target class on `target`. A
+tile that performs a gated action itself (a reaction) reads
+`window.proddashMessaging.unlock.token` and sends it as the Bearer token to
+its own module's route. The Send Message tiles save the chosen platform and
+per-platform destination in their instance settings, so a named layout
+remembers them; the page object is the live copy.
