feat(teams): grant each participant their game's divider role

Reuse the existing CS2/LoL divider roles as participant tags: sync_team_role
now also adds the divider role for the member's team's game, and strips any
other configured divider role (switched game / dropped out). Matched by ID
against config.TEAM_DIVIDERS, so only the divider roles are ever touched.

- TeamSyncResult gains divider_added / divider_removed; summary tallies both
- /teamsync report and log line surface divider_assigned / divider_removed
- tests: grants the game divider, swaps it on a game switch
