refactor(teams): move team-role sync to the economy/community bot

The team-role feature was aimed at the wrong bot. Tournament participants
live in the economy/community guild, but team-role sync had been bolted onto
the dev bot's roster sync (sync_member), which bails out for anyone missing
from the internal member sheet - so it could never reach its actual audience.

Decouple it: keep the (roster-independent) team-sheet parsing, pull the team
wiring off the dev/member-sync path, and re-home it on the economy bot.

- core/member_sync: revert sync_member to add-only (drop team block +
  SyncResult.roles_removed); add roster-independent sync_team_role and a
  whole-guild sync_all_team_roles returning a reporting summary. Still only
  ever touches role NAMES present in the team sheet.
- commands/economy_team_commands: new admin-only /teamsync command.
- bot.py: hourly team_sync_hourly task (economy-only, no-op unless
  TEAM_SHEET_ID is set; first tick at boot covers startup load); register
  /teamsync under the economy profile; drop the dev-side startup load.
- commands/dev_member_commands: /check no longer refreshes teams or reports
  removed roles.
- strings + .env.example: TEAMSYNC_UI, CMD[teamsync], document TEAM_SHEET_ID.
- tests: retarget sync tests to sync_team_role; add sync_all_team_roles case.

+"""Tournament team-role sync for the economy/community guild.
+
+The tournament participants live in the *economy* (community) guild, not the
+internal dev guild, so team-role assignment runs here rather than as part of the
+member-roster sync in :mod:`commands.dev_member_commands`. This is deliberately
+roster-INDEPENDENT: it matches Discord usernames straight against the separate
+registration spreadsheet (``TEAM_SHEET_ID``) and never touches the member sheet.
