Application sending controls: client IP allow-list for authorization, and level-2 rate limits that override the domain ceiling per application.
Added:
- Per-application **client IP allow-list** on the domain page: when enabled,
- SQLite migration `0009_application_auth_ips.sql` (moves legacy trusted IPs
Changed:
- Application level-2 rate limit **overrides** the domain limit for that login
- Domain export/import carries `auth_ip_restrict` / `auth_allowed_ips`; legacy
- Panel help, Settings, and [guide.md](docs/guide.md) describe override semantics
- [guide.md](docs/guide.md): full-backup section documents all four capture
