New server_loop.rs:
- Custom accept loop with pre-connection IP quota check
- DB-based MD5 authentication (verifies user exists + enabled)
- Pre-test user quota check (reject if already exceeded)
- Session tracking in DB (start_session/end_session)
- QuotaEnforcer spawned alongside each test
- Post-test usage recording to both user + IP tables
- Syslog events for auth, quota rejection, test start/end
Full flow:
1. Accept connection → check IP quota → reject if exceeded
2. Handshake + auth → verify user in DB → reject if disabled/not found
3. Check user quota → reject if daily/weekly/monthly exceeded
4. Start session → spawn enforcer (checks every N seconds)
5. Run test → enforcer stops it if quota hit or max_duration reached
6. Record usage → persist to DB → disconnect IP tracker
TODO: Wire actual TX/RX data loops (currently only enforcer runs,
data transfer not yet delegated from pro server to standard handlers)
64 tests, all passing.

New enforcer.rs module runs alongside active tests:
- Periodic quota checks (default every 10s, configurable --quota-check-interval)
- Max duration enforcement — forcefully stops test after limit
- User quotas: daily/weekly/monthly checked against DB + current session
- IP quotas: daily/weekly/monthly checked against DB + current session
- Flush session bytes to DB for accurate cross-session tracking
- Sets state.running=false to gracefully terminate on quota breach
StopReason enum tracks why a test was stopped:
MaxDuration, UserDailyQuota, UserWeeklyQuota, UserMonthlyQuota,
IpDailyQuota, IpWeeklyQuota, IpMonthlyQuota, ClientDisconnected
Tests (6 new, all passing):
- test_enforcer_max_duration: stops after max_duration seconds
- test_enforcer_client_disconnect: detects normal client exit
- test_enforcer_user_daily_quota_exceeded: stops when user quota hit
- test_enforcer_ip_daily_quota_exceeded: stops when IP quota hit
- test_enforcer_under_quota_runs_normally: doesn't stop if under limits
- test_enforcer_flush_records_usage: verifies DB persistence
64 total tests (58 standard + 6 enforcer), all passing.
