Node-page picker and the admin Add form now show, per voice channel, whether
a radio bot can stream there, from S3's voice-check routes:
- Badge per channel: Ready / Needs fix (names the missing permission) /
Couldn't check / Bots busy / No radio bot / Not a voice channel / Limit N.
- The chosen channel shows "<bot> can't Speak in #dispatch: <what removed it>"
plus c2-core's fix sentence, and an expandable per-bot list.
- Footer: "Permissions checked 40s ago · Re-check" (refresh=1, rate limited
server-side; a limited re-check says so). Invite links when no bot fits.
- Start is disabled only on a definite refusal (needs_fix, bad_channel);
unknown fails open. A channel this system already plays in is judged by
the bot that carries it, so Update/move is never blocked by the other bots.
- Admin Add form disables bots that are definitely denied in the bot list.
- 409 refusals (missing_permissions, preferred_busy, preferred_other_node,
bad_channel) are shown verbatim, multi-line.
Org owners (owner decision Q2) get "Radio bot per system" on
Settings > Organization: their own systems, their own BYO bots, set/clear
through S3's PUT /tokens/{id}/prefer/{system}. New GET /tokens/org/preferred
lists only the caller org's systems and bots (no pool bots, no token
strings; a pool bot an admin chose is flagged, not named).
The prefer route now drops the 5-minute doc_get_cached entry for every
system it rewrites, so a new preference applies to the next start.
Stacked on feat/225-s3-perm-check: must merge after S3.
