Standalone endpoint monitors (discussion #6)

Endpoints can now be created directly from the UI, without requiring Docker/K8s labels. Click "New Endpoint" on the Endpoints page to monitor any HTTP or HTTPS URL or TCP host:port.

• Name, target URL, type (HTTP/TCP), and check interval are configurable
• HTTPS targets offer a "Monitor TLS certificate" checkbox that creates a certificate monitor alongside the endpoint
• Standalone endpoints appear in the same grid as auto-discovered ones, with a delete button in the card footer
• Full API support: POST /api/v1/endpoints, PUT /api/v1/endpoints/{id}, DELETE /api/v1/endpoints/{id}

Digest baseline tracking for non-semver tags (discussion #7)

Images using channel tags (lts, alpine, stable, latest) are no longer incorrectly flagged as having a semver update available. Maintenant now tracks remote digests for these tags and detects actual image rebuilds by comparing against stored baselines, instead of suggesting a switch to the latest semver tag.

UI consistency & ConfirmDialog

• Replaced all native browser confirm() dialogs with a custom ConfirmDialog component — dark-themed, accessible (role="alertdialog"), keyboard-navigable (Escape to cancel), with destructive action styling
• Unified delete button placement across all cards (endpoints, certificates, heartbeats) — always right-aligned in a dedicated actions section
• Applied to all 9 components that had delete/cancel actions: cards, channel manager, silence rules, status page managers, webhooks

PWA cache isolation

• Runtime caches are now versioned per build — each deployment gets unique cache names, preventing stale assets from persisting across updates
• sw.js, registerSW.js, and manifest.webmanifest are served with no-cache headers so browsers always fetch the latest service worker
• SPA shell (index.html) also served without caching to ensure immediate pickup of new builds
