test(feedback): DB-backed integration tests — credits, karma, notifications

22 neue Integration-Tests gegen real Postgres, plus auth.users-Cross-
Schema-Joins, plus mock-fetch für mana-credits-Calls. Skip-pattern via
TEST_DATABASE_URL — fresh checkout's bun test passes without a DB.

src/test-helpers/db.ts:
- connectTestDb: drizzle + postgres-js mit voller schema-typing
- seedUser: namespaced 'test-${uuid}' userIds, raw-SQL insert in
  auth.users (cross-schema, kennt mana-analytics nicht alle NOT-NULL
  columns)
- cleanupTestData: FK-aware DELETE chain (notifications → reactions
  → grant_log → feedback → users)
- mockCreditsFetch: globalThis.fetch-shim, captures grant-calls,
  configurable alreadyGranted für idempotency tests

src/services/feedback-credits.integration.test.ts (11 tests):
- submit-bonus: 20+ chars happy path, <20 chars skip, replies skip,
  founder-whitelist skip, rate-limit (11. submit blocked),
  alreadyGranted doesn't write log row
- ship-bonus: +500/+25-emoji-eligible matrix, status-flapping doesn't
  double-pay (idempotent referenceId), founder-author skip
- reaction-bonus: self-react skip, multi-emoji-same-user counts once

src/services/feedback-karma.integration.test.ts (5 tests):
- foreign user reacts → author karma +1
- toggle off → karma -1
- self-react → no change
- floor-clamped at 0
- multi-emoji per user counts separately

src/services/feedback-notifications.integration.test.ts (6 tests):
- author-notify on every status transition
- no notify when status unchanged
- admin_response notify on adminResponse edit
- reactioner_bonus notify on completed transition (+25 in body)
- markRead scopes to caller (stranger can't mark)
- markAllRead only touches caller's rows

Plus:
- package.json: test + test:integration scripts
- schema/index.ts: re-export auth-users so drizzle's type inference
  recognizes the cross-schema model
- CLAUDE.md: full rewrite — endpoints (auth + public), env vars,
  test commands, reward-loop side-effects table

All 38 tests green (16 unit + 22 integration) in 2.35s.
