Implement POST/DELETE /api/overrides endpoints (P1.5)

Add override management API for the training decision system: - POST /api/overrides adds an override (flare, stress, sleep, pms) - DELETE /api/overrides removes an override - Both endpoints use withAuth middleware - Validation for override types, idempotent operations - 14 tests covering auth, validation, and persistence Also fix type error in today/route.ts where DailyLog body battery fields could be null but biometrics object expected numbers. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
