feat: newer version tags, DockPull update banner, flexible scheduling, failure alerts, backups

[StrandedTurtle]

Summary

New features

• Newer version tags. For containers on a version tag (postgres:16.3, app:1.2.0, linuxserver 4.0.14-ls283), DockPull lists the registry's tags. It offers the newest one in the same major version, and the next major if enabled.
  • Tags only compete with tags of the same "shape", so -alpine stays -alpine and -rc/-beta tags never match a stable tag.
  • Switch edits only that service's image: line in the compose file (a .dockpull.bak copy is kept), then updates with the normal health check. A failed pull restores the file, and Revert restores the old tag.
  • Images set via a variable, anchor or digest are refused rather than edited.
  • "Update all" never switches tags. Skip hides one offered tag.
• DockPull update banner. Shows when a newer release is out, with the release notes and the update command. Read-only: DockPull still never touches its own container.
• Scheduling. Daily at a time, or every N hours. A scan missed while the server was off runs about a minute after startup. Settings shows when the next scan is due.
• Failure notifications. A failed or unhealthy update or revert is sent to the configured target (toggle).
• Sign out everywhere. Invalidates every other session; the current device stays signed in.
• Backup / restore. Settings, pins and history as JSON. Restore is validated all-or-nothing and won't duplicate history.
• Release notes for popular images without a source label (curated table plus a linuxserver rule; each repo checked).

Fixes and improvements

• The post-update health check waits as long as the container's own healthcheck needs (previously a fixed 30s), and catches apps that crash a few seconds after starting (previously reported as success).
• Prune leaves revert points unticked by default (opt-in checkboxes).
• Settings saves are now all-or-nothing (a bad value no longer leaves earlier values half-saved).
• Checker tests run the real runCheck against a fake Docker API and registry (re-pushed index, moved tag, local image, newer tags, concurrent checks).

Note: the session cookie fingerprint changed (sign-out-everywhere generation), so everyone logs in once after upgrading.

Testing

• 183 server tests pass; the client builds.
• Live on Docker 29 with a local registry:
  • tag detection, plus compose and standalone switches and reverts (compose file edited, then restored)
  • a failed switch restoring the file
  • crash-after-start detected, with a failure webhook received
  • a 35s healthcheck passing, which the old 30s limit failed
  • sign-out-everywhere, backup/restore, and next-scan scheduling
• New UI screens rendered with Playwright at phone width; no console errors.
