fix: Hash-based tab navigation for direct page access

- Added handleHash() function to read URL hash on page load
- /trades now opens dashboard with Trades tab active
- /income opens Income tab, /streams opens Streams tab, etc.
- Added hashchange event listener for browser back/forward
- Each /page now correctly shows its corresponding tab
