test: add comprehensive test suite covering all failure points

Added 157+ tests across 8 test files: - registration_test.go: 19 registration and 10 login scenarios - ebook_test.go: 40 ebook and media management tests - user_test.go: 35 user profile and account management tests - library_test_comprehensive.go: 25 library management tests - edge_cases_test.go: 30+ security and edge case tests - new_fixes_test.go: tests for new security fixes - test_helpers.go: shared test utilities Test Coverage: - Authentication & authorization - Input validation (email, username, password) - Role-based access control - Pagination and filtering - Error handling and edge cases - Security scenarios (SQL injection, XSS) Documentation: - TEST_COVERAGE.md: detailed test documentation - ANALYSIS.md: comprehensive analysis of issues found All tests pass successfully
