Fix SessionListDialog behavior and document PersistentStorageDialog bug

- Fix SessionListDialog to not reload when user selects a session after deleting others
  - Track if dialog closed via selection vs other means
  - Only call delete callback if not closed via selection
  - Batch deletions to avoid reload on every delete
- Comment out PersistentStorageDialog in both web-ui example and browser extension (TODO: fix)
- Add Known Bugs section to both README.md files documenting PersistentStorageDialog issue
- Clean up navigation tracking variable names in browser extension
