This commit performs a significant cleanup of the codebase by removing unused functions, methods, and entire files across various internal modules. This reduces technical debt and simplifies the project structure. Key changes include: - **cache**: Removed unused cache key generators and metrics snapshots. - **dto**: Removed redundant converter functions and segment creation helpers. - **middleware**: Deleted the unused `logger.go` middleware and simplified `ratelimit.go` and `casbin.go`. - **model**: Removed unused ID helpers, database closing functions, and batch decryption logic. - **pkg**: Cleaned up unused utility functions in `circuitbreaker`, `crypto`, `cursor`, `hook`, and `utils`. - **service**: Deleted `account_cleanup_service.go` and removed unused helper functions in `log_cleanup_service.go` and `sensitive_service.go`. - **repository**: Removed unused private loading methods in `comment_repo.go`.
