fix: handle invalid weather API key gracefully and fix TideDisplay crash

- Fix TideDisplay component crash (use extremes instead of tides)
- Handle 401 weather API errors gracefully (return null data with note)
- Update weather controller to return 200 with null values instead of 503
- Add helpful message about API key activation time
- Fix tide type capitalization (High/Low instead of high/low)
