feat(hobbs-organizer): Shield photo app (com.dayline.photos) + monitoring, links, .100 boot fix

- shield/photos-source: launcher tile + DreamService screensaver showing /photo
  (locked-down WebView, default URL baked in, files/base_url override)
- build-photos-apk.sh: containerized build on hf-pdocker-02 (JDK17, SDK 35);
  signing key kept off-repo on .100 + NAS
- Hobbs-Family-Photos-1.0.apk installed on .186 (canary) and set as its screensaver
- Prometheus probes for /api/health and /api/health/photos; Farm Manager links + group
- CLAUDE.md: .100 left the stale Swarm and its NFS mount waits for network (11-03 outage)
