Migration 0033 widens topics.auth_mode CHECK to include 'session'
alongside 'public' and 'token'.
TopicAuthMode enum gains a Session variant (as_str + from_db
extended uniformly).
RealtimeAuthorityImpl now takes Arc<dyn UsersService> as a third
constructor arg. The Session branch of authorize_subscribe
delegates to UsersService::verify_session_for_realtime(app_id,
token):
* Returns Some(user) → allow. The service bumps the sliding TTL
on success.
* Returns None → Unauthorized.
* Defense-in-depth: even though verify_session_for_realtime
already enforces cross-app isolation, the branch re-checks
user.app_id == app_id.
Tests added (4 new cases): valid session token allows; missing
token is Unauthorized; wrong token is Unauthorized; cross-app
session token is Unauthorized. All 12 realtime_authority tests
pass.
Dashboard: TopicAuthMode TypeScript union widened to include
'session'; the topic create + edit forms gain a third radio option
labeled "session — requires a per-app user session minted by
users::login (v1.1.8)".
picloud binary: construction order reshuffled so users is built
before realtime_authority. app_secrets_repo is now .clone()'d into
the pubsub realtime wiring so the original Arc can be re-used by
realtime_authority.
