Generalize from health-specific to universal personal assistant

The app manages multiple life areas (health, finance, personal, work),
not just health. Updated all health-specific language throughout:

Backend:
- Default system prompt: general personal assistant (not health-only)
- AI tool descriptions: generic (not health records/medications)
- Memory categories: health, finance, personal, work, document_summary, other
  (replaces condition, medication, allergy, vital)
- PDF template: "Prepared for" (not "Patient"), "Key Information" (not "Health Profile")
- Renamed generate_health_pdf -> generate_pdf_report, health_report.html -> report.html
- Renamed run_daily_health_review -> run_daily_review
- Context assembly: "User Profile" (not "Health Profile")
- OpenAPI: generic descriptions

Frontend:
- Dashboard subtitle: "Your personal AI assistant"
- Memory categories: Health, Finance, Personal, Work
- Document types: Report, Contract, Receipt, Certificate (not lab_result, etc.)
- Updated en + ru translations throughout

Documentation:
- README: general personal assistant description
- Removed health-only feature descriptions
