Refine secrets page UI per review feedback

- Remove duplicate secret name/key display in table row; show name only
- Replace mode and status badges with plain text (status uses color only)
- Drop provider vault second line from table
- Change 'Owned by Paperclip' reference to 'Owned'
- Gray out GCP and Hashicorp vault sections with 'Coming soon' label
- Replace inner sheet TabsList with PageTabBar for consistent tab style
- Rename 'Rotate' → 'Update value' for managed secrets
