maziggy 4b46e443dc Fix critical FTP upload failure and revert dangerous exception narrowing ...

The CodeQL cleanup in "Housekeeping" (2b11efd) bulk-narrowed except
clauses across 50+ files, breaking FTP uploads on ALL printer models.
ftplib.error_perm (550 errors) is not a subclass of ftplib.error_reply,
so diagnose_storage() CWD failures escaped the handler and prevented
STOR from ever executing — causing 100% upload failure and HTTP 500s
on /api/v1/archives/{id}/reprint and /api/v1/library/files/{id}/print.

FTP fixes:
- Remove diagnose_storage() from upload hot path
- Change all except (OSError, ftplib.error_reply) to
  except (OSError, ftplib.Error) across bambu_ftp.py

Exception handling reverts (9 files):
- Revert narrowed except clauses back to except Exception in route
  handlers and service code where broad catches are intentional
  defensive programming (archive parsing, HTTP clients, 3MF/ZIP
  processing, Home Assistant, firmware checks)
- Keep narrow exceptions only where safe (single-op blocks like
  int(), file.unlink(), socket.close())
- Remove unused XMLParseError imports from archive.py, threemf_tools.py

Closes #287
