Merge pull request 'Band Lineup 1.12.0: Sync uses Planning Center notes for mics, keeps your moves, and dragging works on touch' (#51) from claude/band-lineup-drag into main

The booth writes each vocalist's and the leader's mic into their Planning
Center note every week ("Mix 8, VOX 5", "Mix 1, Vox 1"), because those
change week to week and the position name ("Vocalist") carries no number.
Sync ignored the notes and dropped the singers onto Vox 2-5 in whatever
order Planning Center listed them.

Sync now reads each team member's note and places anyone whose note names
a spot there first: the mix number must agree with the slot's MIX, and the
role ("VOX 5", "Drums") is scored like a position. "NA" or a blank note
says nothing. Everyone else is placed by position as before. Tests use the
real Oct 25 and Nov 1 notes.

+  starts one, a Go in a group replaces that group's live list, and the
+  first group is the tile's headline — so the tile reads "Message" with

+ *   ch2:64 = Message              only on MIDI channel 2 (otherwise any channel)

+ * Groups: a line "[Colors]" starts a group, and every rule below it belongs

+ * whichever list of that group was live — firing "Blue" ends "Red" — which is

+ * A listen-only RTP-MIDI (AppleMIDI) session participant, in plain Node.
+ *
+ * This is the protocol behind a macOS "Network" MIDI session (Audio MIDI
+ * Setup → MIDI Network Setup) and rtpMIDI on Windows: two UDP ports, a
+ * control port P and a data port P+1. A session sends every MIDI message to
+ * every participant it is connected to, so joining the same session Vista is
+ * in hears exactly the notes Vista hears.
+ *
+ * Both ways of joining work:
+ *  - someone invites us (we show up in Audio MIDI Setup's Directory, or they
+ *    add our address by hand) and we accept anyone;
+ *  - we invite them (`invite(host, port)`), and keep re-inviting until they
+ *    accept, then keep the connection alive with clock syncs.
+ *
+ * We never send MIDI. Packet layouts follow Apple's AppleMIDI session
+ * protocol and RFC 6295 (RTP payload for MIDI).

+ * ProPresenter and the tracks rig fire cue lists through. A session sends
+ * every message to every participant, so this module joins those sessions
+ * as one more participant (rtpmidi.js) and hears exactly what Vista hears.
+ * The admin's "Cue lists" sheet (mapping.js) turns each note into
+ * "Go on Walk-in", "Release Worship 1"…, and from those the module keeps
+ * which lists are live.
+ *
+ *   GET  /state   → { state }                     (instant paint)
+ *   GET  /stream  → SSE: `state` on every change
+ *   POST /clear   → forget which lists are live (when Vista was reset by hand)
+ *
+ * What the tile shows is what Vista was told, not what Vista confirmed: if
+ * Vista is closed or someone works the desk by hand, the two can differ.
