Fix device/replay/session UX issues, add pagination, bump to 0.3.0

- Fix device rename input collapsing on mobile (fixed width vs w-full
  inside an auto-layout table column).
- Add cascade-delete confirmation for sessions with a saved recording.
- Fix header connection LED: derive state from scanning/device-count/
  recording instead of the Buttplug client's raw connected flag; drop
  the label text and hide the indicator entirely when idle.
- Add a per-device disconnect button (stop + remove from store, the
  closest equivalent Buttplug's protocol allows per device).
- Fix replay ending early: duration now comes from the recording's
  actual durationMs, not the last event's timestamp.
- Replay robustness: show which devices are being replayed to, reset
  actuators to zero on start/play/pause, fully disconnect devices and
  the whole client on stop/unmount, surface command failures via toast.
- Stop flagging the header LED red during replay - recording is only
  for live sessions.
- Add page-number pagination to recordings/sessions/devices lists.
- Wordmark SEXY -> Sexy; add proper per-page <title>s including
  dynamic titles for recording/session detail and replay pages.
