fix: replace spinners with skeleton placeholders in Me tabs

- Replace spinner in highlights tab with 'No highlights yet' message
- Replace spinner in reading-list tab with 'No bookmarks yet' message
- Only show these messages when loading is complete and arrays are empty
- Remove unused faSpinner import
- Consistent with skeleton placeholder pattern used elsewhere
