funman300 68d10658c7 fix(economy): close SBC dup-card exploit + non-atomic economy races
Correctness fixes from docs/CORE_CORRECTNESS_ISSUES.md:

- Issue 3 (HIGH, exploit): submit_sbc dedups owned_card_ids (HashSet) and
  bounds the list (MAX_SBC_CARDS=30) before resolution. A repeated id resolved
  the same card N times, passed validation, and granted the reward while only
  one card was consumed -> any SBC satisfiable with one duplicated card = free
  reward. Now rejected with BadRequest. Regression test added.
- Issue 2 (HIGH): TOCTOU economy mutations closed with single-statement
  compare-and-swap (no transaction plumbing): club::spend_coins conditional
  debit (WHERE coins >= ?) + rows_affected, also rejects negative amounts;
  pack::open_pack claims the pack before minting; market::buy_listing claims
  the listing before charging and releases on debit failure; market::sell_card
  guards the DELETE with owner + rows_affected; checkin::claim uses a
  conditional INSERT ... WHERE NOT EXISTS (today) before paying out.
- Issue 4 (LOW): season.rs .expect() on missing rows -> graceful AppError;
  checkin index (streak-1) % 7 -> .rem_euclid(7) (guards negative index panic).
- Issue 1 (LOW): migration 0019 adds sbc_submissions.club_id + backfill;
  submit_sbc binds it so the MY CLUB milestone query stops silently reading 0.

Core suite 179 green + clippy clean.

-- Issue 1: sbc_submissions was created (0001_initial.sql) without a club_id column,
-- but the MY CLUB milestone query (routes/club.rs get_milestones) counts
-- SELECT COUNT(*) FROM sbc_submissions WHERE club_id = ? AND passed = 1
-- so SQLite errored on the unknown column and the error was swallowed by
-- `.unwrap_or(0)` -> the `sbcs_completed` milestone always read 0. Add the column
-- and backfill it from the profile's club so historical submissions count.
ALTER TABLE sbc_submissions ADD COLUMN club_id TEXT;
UPDATE sbc_submissions
SET club_id = (SELECT c.id FROM clubs c WHERE c.profile_id = sbc_submissions.profile_id)
WHERE club_id IS NULL;
