- discord_oauth: POST /discord/oauth/start and GET /options take an optional
system_id. The system must be the org's own or shared (another org's or
unknown = 404). Its preferred bot is strict: one that can't connect is a
404, never a quiet swap to Automatic. No preference = the usual order.
The picker's "bot for a system" now always sends system_id.
- #257: _channel_state gives a bot whose token Discord rejected its own
"invalid" state; the picker shows "Radio bot needs replacing" with no
invite links, instead of "No radio bot".
- #256: Start no longer stays disabled on "Needs fix". It re-checks with
Discord first (refresh=1) and starts only if the fresh answer allows it.
"Not a voice channel" still disables Start.
- #258: own tooltip for "Not a voice channel"; "platform admin" -> "DRB
support"; PreferredBotsCard says plainly that adding your own bot isn't
self-serve (no support address exists yet, see #47), and a load failure
gets a plain message + Try again instead of the raw C2 error.
