feat(hobbs-organizer): v1.1.0 password-protected LAN-only admin for calendar links

- /admin: first-visit password setup (scrypt), signed 30-day session cookie,
  calendars add/remove/reorder/rename/color/hide, masked URLs, per-feed test,
  history (20) with restore; /photo-admin -> /admin#photos placeholder
- settings in local /data (settings.json + auth.json + history/), seeded once
  from the calendar secret; dashboard + health read from settings
- start.mjs drops privileges after reading secrets and runs a front proxy that
  stamps the real client IP; admin refuses non-LAN and proxied requests
- deploy: HOBBS_DATA_DIR=/var/lib/hobbs-organizer/data, image 1.1.0 (1.0.0 kept)
