Add unit and integration tests for scan progress tracking (Step 8)

Implements comprehensive test coverage for the backend scan progress tracking
feature added in previous commit.

Unit Tests (internal/services/worker_test.go):
- TestWorker_JobResult_HasStatsFields: Verifies JobResult stores new stats fields
  - Tests FilesScanned, NewItems, Errors are properly stored
  - Confirms values are retrievable via GetJobStatus()
- TestWorker_ProgressCallback_UpdatesJobResult: Verifies real-time updates
  - Tests progress callback mechanism updates JobResult
  - Confirms multiple incremental updates work correctly
  - Validates callback updates all stat fields

Integration Tests (cmd/server/tests/scanner_integration_test.go):
- TestScanProgress_TracksStatistics: End-to-end scan progress tracking
  - Creates library with folder via API
  - Triggers scan and polls status endpoint
  - Verifies new fields (files_scanned, new_items, errors) exist
  - Confirms values are non-decreasing during scan
  - Validates progress reaches 100% on completion
- TestScanProgress_BatchingWorks: Verifies batching reduces updates
  - Creates library and triggers scan
  - Counts distinct files_scanned updates
  - Confirms fewer updates than files (batching working)

Test Design:
- Uses setupTestServer() from test_helpers.go (PROJECT_GUIDELINES.md compliant)
- Single shared test setup per suite (no connection pool exhaustion)
- Safe type assertions with require.True() for JSON responses
- Polls for up to 30 seconds with 1-second intervals
- Tests compile successfully and run in container only

Coverage:
- Unit tests: JobResult storage, callback updates
- Integration tests: End-to-end API behavior, batching verification
- All new code paths covered by tests

Files modified:
- internal/services/worker_test.go (added 2 tests)
- cmd/server/tests/scanner_integration_test.go (new file, 254 lines)
