test: add comprehensive media-item ISBN validation tests

New test file with 5 test suites:
- TestMediaItemISBNNormalization (8 test cases)
- TestMediaItemISBNEdgeCases (3 test cases)
- TestMediaItemsPagination (5 test cases)
- TestMediaItemLibraryRequirement (2 test cases)
- TestUpdateMediaItemISBN (1 test case)

Features:
- Tests use /api/media-items endpoint (not deprecated /api/ebooks)
- Real API calls (not mock handlers)
- Comprehensive ISBN-10/ISBN-13 normalization coverage
- Pagination validation with limit/offset edge cases
- Library requirement validation

This replaces the functionality lost from isbn_and_library_test.go
with modern, working tests using current API endpoints.

Phase 3: Test Suite Cleanup - Replacement Tests
