Fix: Correct all database model names from camelCase to snake_case

- Fixed ai-analytics API: Created missing endpoint and corrected model names
- Fixed ai-learning-status.ts: Updated to use ai_learning_data and trades models
- Fixed batch-analysis route: Corrected ai_learning_data model references
- Fixed analysis-details route: Updated automation_sessions and trades models
- Fixed test scripts: Updated model names in check-learning-data.js and others
- Disabled conflicting route files to prevent Next.js confusion

All APIs now use correct snake_case model names matching Prisma schema:
- ai_learning_data (not aILearningData)
- automation_sessions (not automationSession)
- trades (not trade)

This resolves 'Unable to load REAL AI analytics' frontend errors.
