Reduce copilot scroll stickiness for consistent, less-sticky behavior

- Changed default stickinessThreshold from 100 to 30 in use-scroll-management.ts
- Removed explicit stickinessThreshold override (40) from copilot.tsx
- Both copilot and chat now use the same default value of 30
- This makes scrolling less sticky across all copilot message interactions
