Close Gitea signup, dedup posture-check alerts, extend Borg scope

Operational hardening across several services after live incident
analysis between 2026-05-18 and 2026-05-20:

- Gitea: disable public registration and OpenID signup/signin to
  stop the external POST / 5xx bursts that triggered availability
  alerts. New repo-wide policy requires every productive
  Micha/homelab-infra Komodo stack to ship with an active
  Gitea->Komodo webhook on the current stack ID (documented in
  CLAUDE.md, AI_CONTEXT.md, WORKFLOW.md).
- posture-check: extract the Disk1 fstype check into its own
  function so the documented Disk1 NTFS exception no longer raises
  ntfy warnings, skip POSIX inode checks on NTFS, and dedup ntfy
  alerts via a fingerprint state file with ALERT_REPEAT_SECONDS
  (default 24h). Repeat-spam on the same cause now suppressed.
- docker-critical-events: parse the event JSON for container name,
  action, exit code and signal; drop `die exit=0` events (clean
  stops); ship a structured ntfy message instead of the raw event
  line.
- Borg UI: mount /mnt/user/services into the backup container as
  /local/services:ro and include homelab-infra, stacks and
  posture-check in all-important-sources.txt. RESTORE_MATRIX and
  DISASTER_RECOVERY updated accordingly.
- Unraid user scripts: document the new
  homelab-operations-report-daily cron job and the SMTP password
  file it expects on the host.
- MIGRATION_LOG: capture the four live events from this window -
  Gitea 5xx burst + signup closure, Komodo webhook reconciliation,
  posture-check host-version verification, Borg scope extension,
  and Traefik 5xx alert detuning.
