Divider placement matched the divider role by its exact Discord name, so
renaming the role in Discord silently broke positioning. Switch the
TEAM_DIVIDER_<SUFFIX> config to hold a role ID; resolve the ID to the
role's current name in apply_team_role_positions and keep the existing
name-based ordering maths downstream unchanged.
- config._parse_team_dividers now parses values as ints (rejects non-ints)
- resolve_divider / _team_divider cache / get_team_dividers return IDs
- apply_team_role_positions resolves each ID via guild.get_role once
- .env.example documents IDs and ships the CS2/LoL divider role IDs
- resolve_divider tests updated to assert IDs
