Add trace-level logging to show the logical path of CSRF token processing
- Log token source (header or parameter) in resolveCsrfTokenValue
- Log request attribute names in handle methods
- Log failures in XorCsrfTokenRequestAttributeHandler (especially Base64 decoding)
- Add similar logging to XorServerCsrfTokenRequestAttributeHandler
Improves debugging capabilities without changing functionality.
