feat(import): add structured statusCode to ImportStatus — replaces raw German message

Browse Source 
Adds a statusCode field (IMPORT_IDLE / IMPORT_RUNNING / IMPORT_DONE /
IMPORT_FAILED_NO_SPREADSHEET / IMPORT_FAILED_INTERNAL) to ImportStatus.
The frontend will map these codes to localized strings via Paraglide
instead of rendering the backend's German message verbatim.

NoSpreadsheetException distinguishes a missing spreadsheet from other
I/O failures so the frontend can show a specific error without raw text.
