♾️ fix: Permanent Ban Cache and Expired Ban Cleanup Defects (#12324)
* fix: preserve ban data object in checkBan to prevent permanent cache

The !! operator on line 108 coerces the ban data object to a boolean,
losing the expiresAt property. This causes:

1. Number(true.expiresAt) = NaN → expired bans never cleaned from banLogs
2. banCache.set(key, true, NaN) → Keyv stores with expires: null (permanent)
3. IP-based cache entries persist indefinitely, blocking unrelated users

Fix: replace isBanned (boolean) with banData (original object) so that
expiresAt is accessible for TTL calculation and proper cache expiry.

* fix: address checkBan cleanup defects exposed by ban data fix

The prior commit correctly replaced boolean coercion with the ban data
object, but activated previously-dead cleanup code with several defects:

- IP-only expired bans fell through cleanup without returning next(),
  re-caching with negative TTL (permanent entry) and blocking the user
- Redis deployments used cache-prefixed keys for banLogs.delete(),
  silently failing since bans are stored at raw keys
- banCache.set() calls were fire-and-forget, silently dropping errors
- No guard for missing/invalid expiresAt reproduced the NaN TTL bug
  on legacy ban records

Consolidate expired-ban cleanup into a single block that always returns
next(), use raw keys (req.ip, userId) for banLogs.delete(), add an
expiresAt validity guard, await cache writes with error logging, and
parallelize independent I/O with Promise.all.

Add 25 tests covering all checkBan code paths including the specific
regressions for IP-only cleanup, Redis key mismatch, missing expiresAt,
and cache write failures.
