fix: resolve remaining SonarQube issues

- Remove operator == and != overloads from Entity<T>
- Replace Count() with Any() in RecommendationService for performance
- Change ToActionResult return type from IActionResult to ObjectResult
- Rename userClaims to user in AuthService to match interface
- Extract GetSigningKey() method in JwtTokenService to reduce direct config access
