add TSS API endpoints + web proxy (#1234)

Adds /api/tss/teams/* and /api/tss/leaderboard/teams to SREBOT/server.js,
reading tss_battles.db and tss_teams.db with queries adapted to the
team_id / team_name / teams_data schema. Mirrors the existing
/api/squadrons/* endpoints. SREBOT/web/server.js gains matching proxy
routes so the frontend can reach them via the website host.

TSSBOT/BOT/storage.py picks up the columns and table the endpoints need
to return meaningful data: teams_data.clanrating, team_members.points,
and a new teams_points history table. All idempotent under the existing
init_tss_dbs() call.
