Add dashboard error handling, seed data, and Docker host Ollama wiring

- Wrap getDashboardSnapshot in try/catch; return JSON 500 instead of crashing
- Add prisma/seed.ts with realistic Feb + Mar 2026 data: biweekly $2,850 pay
  schedule, $2,430 rent, expenses across all 8 categories
- Update Dockerfile and backup route for host Ollama runtime
