fix(sidebar): fix PR hint for fork PRs, remove badge styling, add hover effect

- Replace REST API PR lookup with `gh pr view` which handles fork PRs
- Fix state comparison to use lowercase (matching server output)
- Remove pill/badge styling, show plain icon + #number
- Add brighter hover colors and underline for clickability hint
