Improve scraper robustness for Great Bear (YCGBR)

Changes:
- Increased page load timeout to 60s
- Increased table wait timeout to 45s
- Added longer sleep (8s) for dynamic content
- Improved table detection to look for 'Date/Time' or 'Date' headers
- Added console logging for debugging
- Changed Great Bear ID back to YCGBR with better scraper

The scraper now waits longer and is more flexible in detecting data tables,
which should resolve issues with slower-loading stations like Great Bear.
