fix(teams): the two defects the phase 9 rig walk found

Walked against real MariaDB, the real app, and a fake standing in for Discord
that mounts the bot's real internal routes — everything up to the Discord API
call was production code. 47 assertions, and it found two things every unit
test in the phase had passed over.

1. **Every query failed: two result columns named `team_id`.** `desiredTeams`
   and `holdersWithoutClaim` both select `t.id AS team_id`, and the shared
   column list added `i.team_id` beside it. The `mariadb` driver refuses a
   result set with a repeated field name outright, so the pass died at its
   first query with "Error in results, duplicate field name `team_id`" — on the
   one code path every unit test stubs.

   It was also the wrong column: `desiredTeams` LEFT JOINs, so `i.team_id` is
   NULL for exactly the Teams that have no channel yet, which is the create
   case. The two queries that do not join `teams` now ask for it by name.

   The regression test checks the INTERPOLATED sql captured from a fake
   `query`, not the source text — in the source the shared list is still a
   `${COLUMNS}` placeholder, and a first attempt that read the file passed
   happily with the bug reintroduced.

2. **"Sync now" said "Nothing was done" while it was doing it.** Saving the
   settings with voice switched on asks for a pass. An operator who then
   presses Sync now — the obvious next thing — hit `running` and got back
   `ran: false, reason: "a pass is already running"`, which the panel renders
   as nothing having happened, while the pass they triggered was busy creating
   their channels. A pass in flight is now JOINED and its real outcome
   returned, the same choice `teamSync.reconcileNow` makes for the same reason.
