fix: vendor_33 BLE emits compatible 'status' event for existing pages

- handleValueChange now calls parseVendorStatus and emits 'status'
  with legacy-compatible shape (mode_state, battery, remaining_ms, etc.)
- 1-byte heartbeat mapped to mode_state, 33-byte state parsed for
  active IO detection
- Fixes regression where treating, index, wear-check, auto-scan pages
  never received status updates in vendor_33 mode
- Also emits 'vendor_raw' with full parsed data for future use
