Expanded the e2e test suite and fake device data

- fake_records now generates a full year (2026) of classic workday
  punches (09:00-13:00, 14:00-18:00) for the employees in fake_users;
  this spans many 1024-byte blocks, exercising the multi-block
  streaming path
- fake_users/fake_records are now public so tests can assert against
  them instead of hardcoded expectations
- scoped #[allow(clippy::unwrap_used)] to only the functions that
  actually use unwrap, instead of a blanket file-level allow
- added gets_total_record_count, streams_records, and
  gets_none_for_unknown_employee tests
