- Standardize paths across containers
- Update API URLs to use container hostnames

Features:
- Remove redundant directory creation logic
- Simplify path resolution in frontend
- Add better error handling for file operations
- Use container networking DNS resolution

Technical Updates:
- Change API_BASE_URL to use service name: kenyare-backend:8000
- Remove fs operations from consts.ts
- Update path handling in saveFile function
- Add detailed error logging
- Fix directory permissions
