feat: batch preset send mode

- Toggle between single and batch mode with a button
- Batch mode: multi-select presets, shows selected preset list
- Batch send: sends all selected presets sequentially with progress
- Progress indicators: pending → sending (spinner) → success (✓) / error (✗)
- Single mode: unchanged UX with topic/payload/QoS/Retain editors
- Both modes share variable bindings and v5 properties
