chore: finalize audit-based hardening.

- Standardized all datetime calls to UTC across database and reporting.
- Fixed lexical typos in brain decision prompts.
- Refined en-UK regional routing detection with linguistic heuristics.
- Expanded CorrectionFeedback schema for 100% accurate user attribution.
- Verified 63/63 passing tests with zero linting issues.
