fix: resolve TypeScript errors and eliminate manual coordinate hardcoding

- Fix sendEmail function call to use proper EmailOptions object
- Improve GeographicMap by replacing 52 hardcoded coordinates with automatic extraction from @rapideditor/country-coder library
- Fix test imports to use correct exported functions from lib modules
- Add missing required properties to Prisma mock objects in tests
- Properly type all mock objects with correct enum values and required fields
- Simplify rate limiter mock to avoid private property conflicts
- Fix linting issues with variable declarations and useEffect dependencies
