Bump version to v0.2.3 — per-channel sync visibility & controls

Documentation + version bump for the live-channel follow-up shipped in 6807240
(per-channel last-synced badges via recipe_state.json, the per-channel
"Save & Sync now" button, and the Dashboard "next run" indicator).

- frontend/package.json: 0.2.2 -> 0.2.3 (shown in the UI sidebar).
- CHANGELOG.md: verbose 0.2.3 entry covering the new per-channel state, scoped
  /api/recipes/run?only=N, next_run_seconds, and the documentation reconciliation
  that captured source/target agnosticism as an explicit (unbuilt) future goal.

Verified in Docker: image rebuilt from source, boots clean on 7979, and 0.2.3 is
present in the built frontend bundle.

+## [0.2.3] — 2026-06-04
+
+Follow-up to the Live Channels release: per-channel visibility and control that the
+original plan called for but v0.2.2 only partly delivered.
+
+### Added
+
+- **Per-channel "last synced" badge.** Each live channel row on the Channels page
+  shows when it was last checked ("synced 2h ago" / "never"). Backed by a new
+  cosmetic `data/recipe_state.json` — written by the scheduler, read by the UI. It
+  is **not** correctness state (the change-detection diff still reads live Tunarr);
+  it lives in its own file so it never races with `channels.json` edits or deploys.
+- **Per-channel "Save & Sync now".** The channel editor (for live channels) gains a
+  button that saves the channel and immediately runs a scheduler cycle scoped to
+  just that channel (`/api/recipes/run?only=N`), applying the recipe to Tunarr in
+  place without leaving the editor.
+- **"Next run" on the Dashboard.** The Auto-Updates card now shows when the next
+  automatic check will run (e.g. "next ~in 11h"), alongside the last check.
+
+### Changed
+
+- `/api/recipes/status` now returns `next_run_seconds` and a per-channel `channels`
+  map. The scheduler's last-run timestamp moved to wall-clock time so the status
+  endpoint can compute the next run without touching the event loop.
+
+### Notes
+
+- Documentation reconciled against the full original plan: source/target
+  agnosticism (Jellyfin source, ErsatzTV target) is captured as an explicit
+  **future** goal with the in-place-update contract noted, but intentionally not
+  built yet — there's no second source/target to validate an adapter layer against.
