Admin PIN: the fields say enough

The paragraph under the PIN fields explained what the PIN covers and how to
clear it by hand — and only someone already past the PIN could read it, so
the recovery note was never where it was needed. Gone, with the dead style
and the element lookup that hung off it.

The live line under the heading stays: it is the only thing that says
whether admin is locked, and the only warning that a passcode in the
server's environment outranks whatever is set here.

-| `adminPasscode` | If set, the admin page asks for this shared passcode. Leave `""` for none — it's a plain-HTTP LAN tool. |
+| `adminPin` | The admin PIN, as a scrypt hash. **Set it in the admin page's Admin PIN section**, not by hand — 6 digits, and only the hash is stored. Absent means admin is open to anyone on the network. |
+| `adminPasscode` | An older free-text passcode. Still honoured, so an existing install keeps working; new installs should use `adminPin`. |
 | `forge` | Where updates and module installs are fetched from. Absent or `"github"` uses GitHub; a Gitea or Forgejo base URL such as `"http://10.3.8.90:3000"` uses a server of your own. Set it per machine in the data directory, alongside `repo`. |
 | `theme` | The dashboard palette: `booth` (default), `harbor`, `graphite`, `ember` or `daylight`. The admin page's **Theme** section writes this one — see [Themes](#themes). |
