Paul Bailey b0eafebfc4 feat: implement GBIF biodiversity API integration (partial)
- Add GBIF API integration for marine species observations
- Implement species categorization (birds, fish, mammals, algae, etc.)
- Add Marine Protected Area detection for 7 Irish MPAs
- Determine habitat types from observations
- Add BiodiversityInfo component back to EnvironmentalDataPanel
- Free API, no key required

Note: GBIF API parameters need adjustment - currently returning 400 error
