This commit addresses numerous linting errors and improves overall code quality.
- Fixed dozens of 'errcheck' violations by adding error handling and logging for ignored errors, particularly in analytics goroutines and test setup.
- Resolved 'ineffassign' and 'staticcheck' warnings by refactoring variable scopes and suppressing intentional-but-flagged test patterns.
- Removed dead code identified by the 'unused' linter, including helper functions and mock services.
- Refactored test suites to fix inheritance issues, consolidating GraphQL integration tests and correcting test setup logic.
- Corrected invalid logging calls that were causing type check failures.
The codebase now passes 'make lint-test' cleanly.
