Add support for configurable identity attributes in mTLS authentication,
allowing identity extraction from CommonName, Subject DN, Email SAN,
URI SAN, or DNSName SAN with fallback chain support. Includes regex
pattern matching for URI SANs (e.g., SPIFFE workload IDs).
- Add MTLSConfig with identity attributes, URISANPattern, and index fields
- Implement extractMTLSIdentity with fallback chain logic
- Move the mtls tests in the api package to pkg/api/mtls_test.go

- Refactored HTTP client from global cache to struct-based approach (global state was shared between tests, including what certificates to use)
- Enhanced pkg/test/tls to support ECDSA and ED25519 key types
- Replaced static certificate files with dynamic generation in golang tests
- Fixed test cleanup issues and improved resource management
This eliminates dependency on external cert generation scripts and
improves test maintainability.

* feat: support mTLS-only authn/authz with AccessControl and allow combining mTLS with other auth mechanisms

* refactor: improve authentication logic and TLS certificate generation
- Fix mTLS authentication to use only leaf certificate instead of iterating
through all certificates in the chain
- Reject Authorization headers when corresponding auth method is disabled,
regardless of mTLS status (security improvement)
- Simplify authentication switch statement ordering and logic
- Move ErrUserDataNotFound error handling into sessionAuthn method
- Refactor TLS certificate generation to use Options pattern with
CertificateOptions struct for better extensibility
- Consolidate duplicate certificate generation code into helper functions
(generateCertificate, parseCA, initializeTemplate, applyOptions)
- Rename certificate generation functions for clarity:
- GenerateCertWithCN -> GenerateClientCert
- GenerateSelfSignedCertWithCN -> GenerateClientSelfSignedCert
- Add support for SAN settings including email addresses in certificates
- Update tests to reflect new authentication behavior and certificate API
This commit improves both the security posture (rejecting disabled auth
methods) and code maintainability (consolidated certificate generation).
