v10.1.7-alpha — Caddy reboot resilience, proactive update emails, Search Containment plugin

Servers reliably come back after a reboot, you get emailed when updates are waiting, and SAR teams get a new containment tool

Caddy reboot resilience. On some servers — especially small edge boxes on DHCP — the web front end (Caddy) could fail to start after a reboot because it came up before the network was ready, taking down every site behind it (the map, TAK admin, SSO, portal) until someone manually restarted it. That's fixed: Caddy now waits for the network to be online and self-recovers if it still loses the race, so a server returns to full service on its own after a power loss or reboot — no console, no SSH needed. Validated across Ubuntu 22.04, Rocky/RHEL 9, and ARM64.

Proactive update emails. The console now emails you — through the same alerting path Guard Dog already uses — when an update is pending: a CloudTAK plugin, CloudTAK itself, or the console. You find out without having to open the page, and you get one email per new version, not a reminder every hour.

New plugin: Search Containment. An ATAK Chokepoint-style tool for search and rescue is now installable from the CloudTAK plugins panel. Pick a shape, line, or a point on the map, set a containment distance, and it drops numbered markers wherever the trail network crosses the ring — posted straight into the active mission for the whole team.

Also in this release: a clear "dev" marker on plugin cards for boxes that track a plugin's test channel.

Upgrade: applied automatically on the next console update. Healthy boxes are left untouched.
