This PR simplifies the IndexedDB synchronization mechanism by removing
individual sync controllers and services, and instead using Inertia.js
shared props to provide data globally across the application.
## Benefits
1. **Simplified Architecture**: Removed complex sync logic for
static/semi-static data (accounts, categories, banks, labels, automation
rules)
2. **Better Performance**: Data is now shared via Inertia props,
eliminating unnecessary API calls and IndexedDB operations
3. **Reduced Complexity**: Significantly reduced codebase size (~2000
lines removed)
4. **Better UX**: Data is immediately available on page load without
waiting for sync operations
5. **Maintainability**: Fewer moving parts means easier to maintain and
debug
## Migration Notes
- Transaction syncing still uses IndexedDB for offline support
- All other data (accounts, categories, banks, labels, automation rules)
is now fetched via Inertia shared props
- Components automatically receive updated data on navigation without
manual sync operations
Allow users to select individual transactions for import instead of
automatically importing all non-duplicate transactions. Adds checkboxes
to the preview table with select-all functionality and updates the
import logic to only process selected transactions.
