fix: rebuild bundle with widget, restore TOTP across container recreate, integrate auto-updater changes

Three logical changes grouped:

1. Widget bundle rebuild + sami-files logo (from previous session)
   - status/dist/{init,core,features,onboarding}.js rebuilt from latest source
   - status/sw.js cache bumped to dashcaddy-shell-594ec75648 to force SW refresh
   - status/assets/sami-files.png added (Sami Files service card logo)

2. status/build.js: include monitoring-widgets.js in bundle
   - The original build.js was missing monitoring-widgets.js from its JS()
     bundle list — that's why the System Overview widget never showed up
     in the live init.js until we ran the live /var/www/dashcaddy-status/
     build.js. Now consistent.

3. dashcaddy-api/scripts/dashcaddy-update.sh restart_container(): preserve
   TOTP secret across container recreates
   - Was only setting SERVICES_FILE; container fell back to image-local
     /app/credentials.json + /app/.encryption-key (auto-generated fresh
     every recreate), which broke TOTP for the bind-mounted secret at
     /app/data/credentials.json
   - Added CREDENTIALS_FILE + ENCRYPTION_KEY_FILE env vars pointing at
     /app/data/ so the container reads from the bind-mounted host data dir
   - See skill: software-development/dashcaddy/references/totp-and-system-overview-pitfalls.md §9

4. Auto-updater integration (pulled from upstream release):
   - dashcaddy-api/VERSION: dev → c64bbe2
   - dashcaddy-api/health-checker.js, middleware.js, package.json,
     routes/backups.js, src/app.js: new release code (bundled workflows,
     /api/auth/ → /api/v1/ back-compat rewrite, backup storage limits)
