feat(zones): profile-scoped groups, zone modes, sequence brightness

- Optional profile_id on groups; UI and API for shared vs profile-only groups\n- Zone content_kind (presets vs sequences); edit modal shows matching sections; devices via groups only\n- Server sequence playback folds zone brightness into preset wire b (per MAC where needed)\n- Related preset/sequence/audio/beat-route and client updates Co-authored-by: Cursor <cursoragent@cursor.com>
feat(ui): edit tab zones, audio readout, live reload

+2. When adding a new pattern, ensure led-controller has `db/pattern.json`; if it does not exist, create it. Add the new pattern metadata and parameter mappings there. Optionally set **`supports_manual`** to `false` when the pattern is a poor fit for manual mode or audio beat triggers (smooth/blended animations); omit or `true` otherwise.
 3. When adding a new pattern, add at least one test preset entry in `db/preset.json` in led-controller that uses the new pattern.
 4. For any pattern that supports both auto and manual modes, keep behaviour parity unless explicitly requested otherwise: background colour handling, colour-cycling order, and parameter timing semantics (e.g. `n2`/`n3` meaning) must match between auto and manual paths.
