feat: add random task jump hotkeys and document navigation keys

- Add hotkey '1' to jump to a random pending task
- Add hotkey '2' to jump to a random pending task without due date
- Both hotkeys include visual feedback with blink animation
- Document '0' key as synonym for 'g' and 'Home' in help screen
- Update help screen navigation section with all new hotkeys
