test: Improving tests coverage for McpUriTemplateManager

[alxkm]

Summary

Adds 8 new test cases to improve test coverage for McpUriTemplateManager functionality, focusing on real-world scenarios and edge cases.

Tests Added

• Special characters handling: Tests variable values with @, -, . characters (emails, filenames)
• Complex nested paths: Multi-level API paths with 3+ variables
• Path matching validation: Ensures incorrect segment counts and static segments don't match
• Variable positioning: Tests variables at path beginning (version prefixes)
• Simple cases: Single variable templates and root-level variables
• Adjacent variables: Consecutive variables without static separators

Coverage Improvements

• Real-world scenarios: Covers common API patterns like /api/v1/org/{id}/project/{id}
• Edge case protection: Root paths, consecutive variables, special characters
• Regression prevention: Ensures matching logic works correctly for various path structures
• Documentation: Tests serve as usage examples for the URI template manager

Testing

All new tests pass and complement existing test suite coverage.
