Complete hardware fingerprint elimination

Removes all remaining hardware fingerprint validation logic to fix system
startup errors and improve cross-hardware compatibility.

Key changes:
- Remove hardware compatibility checks from database-file-encryption.ts
- Remove backup restore hardware validation from database.ts
- Remove database initialization hardware checks from db/index.ts
- Delete hardware-fingerprint.ts module entirely
- Update migration files to use fixed identifiers

Fixes "wmic is not recognized" and "Hardware fingerprint mismatch" errors
that were preventing system startup and database operations.
