* fix(#219): add pagination to sessions history tab
The /api/sessions endpoint was called without pagination params, so the server returned only its default limit of 20 sessions.
- SessionListResponse: added total/limit/offset fields from server response
- HermesApiService: added @Query params (limit, offset, order) to getSessions()
- SessionsViewModel: added loadMore() that appends pages, hasMore derived from total
- SessionsScreen: added 'Load more sessions' button + loading spinner at bottom of list
* chore: remove plan file from git
* fix: compilation errors in sessions pagination
* chore: gitignore plan files
* fix: remove duplicate brace
