Fix Detekt Kotlin version compatibility issue

- Downgrade Kotlin from 1.9.25 to 1.9.23 to match Detekt 1.23.6
- Update Detekt configuration to remove deprecated properties:
  * Replace ComplexMethod with CyclomaticComplexMethod
  * Remove deprecated rules (DataClassContainsFunction, MissingWhenCase, etc.)
  * Fix ForbiddenComment configuration (values -> comments)
  * Replace deprecated brace rules with current equivalents
  * Fix excludedFunctions format from string to array
  * Remove formatting section (deprecated configuration)

This resolves the GitHub Actions build failure where detekt was compiled
with a different Kotlin version than the project.
