Complete the import flow from file upload through duplicate resolution
to transaction creation. Previously, ResolveDuplicatesAsync was a stub
that only incremented counters, FileWatcherService detected files but
didn't process them, and ImportsView.vue ignored the API response.
Backend:
- Add ParsedDataJson column to ImportBatch to persist parsed data
between upload and confirm steps
- Rewrite ImportService.ResolveDuplicatesAsync to deserialize parsed
transactions and create/merge/skip based on user decisions, with
payee matching, fingerprinting, and account balance updates
- Add GetBatchesAsync for import history
- Complete FileWatcherService: wait for file ready, resolve account by
filename, call UploadAsync, send SignalR notification, archive file
- Add GET /api/imports/batches endpoint
Frontend:
- Create imports API service (frontend/src/services/imports.ts)
- Add ImportBatch, DuplicateResolution types
- Rewrite ImportsView.vue with 3-step Vuetify stepper wizard:
upload, review with duplicate handling, completion summary,
plus import history table
