NEW-1: add_header in location /api block suppressed server-level security
headers (HSTS, CSP, X-Frame-Options, etc). Duplicate all security headers
into the /api block explicitly per nginx inheritance rules.
NEW-2: Add 0.0.0.0/8 to _BLOCKED_NETWORKS — on Linux 0.0.0.0 connects
to localhost, bypassing the existing loopback check.

- W-01: Update README.md security section to reflect removed in-memory
rate limiter and add /setup to nginx rate-limited endpoint list
- W-02: Replace misleading ALLOW_LAN_NTFY reference with actionable
guidance to edit _BLOCKED_NETWORKS directly
- S-04: Add comment explaining burst=3 on /api/auth/setup vs burst=5

- Remove ineffective in-memory IP rate limiter from auth.py (F-01):
nginx limit_req_zone handles real-IP throttling, DB lockout is the per-user guard
- Block RFC 1918 + IPv6 ULA ranges in ntfy SSRF guard (F-02):
prevents requests to Docker-internal services via user-controlled ntfy URL
- Rate-limit /api/auth/setup at nginx with burst=3 (F-06)
- Document production deployment checklist in .env.example (F-03/F-04/F-05)

Remove RFC 1918 blocks from _BLOCKED_NETWORKS — only block loopback
and link-local. Self-hosted ntfy servers are typically on the same LAN.

- Add ntfy columns to Settings model (server_url, topic, auth_token, enabled, per-type toggles, lead times)
- Create NtfySent dedup model to prevent duplicate notifications
- Create ntfy service with SSRF validation and async httpx send
- Create ntfy_templates service with per-type payload builders

- Register scheduler in main.py lifespan with max_instances=1
- Update SettingsUpdate with ntfy validators (URL scheme, topic regex, lead time ranges)
- Update SettingsResponse with ntfy fields; ntfy_has_token computed, token never exposed
- Add POST /api/settings/ntfy/test endpoint
- Update GET/PUT settings to use explicit _to_settings_response() helper
- Add Alembic migration 022 for ntfy settings columns + ntfy_sent table
