feat(frontend): add text-capture form to CaptureDialog

- Add submitTextCapture API client function with same error handling as submitCapture
- Create makeTextItem() factory for text capture state
- Implement CaptureTextRow component with title, body textarea, and MIME selector
- Add 'Add text' button in capture dialog toolbar
- Update handleArchive to filter and route text submissions
- Modify submitBgJob to detect and submit text items via submitTextCapture
- Skip probe and conflict checks for text items
- Reuse job tracking and batch settlement for text captures
