Enhancement: windowed pagination

introduce a window-fetching approach instead of this cursor one. E.g., fetch notes from start_cursor to end_cursor (or a plain limit on the number of notes). Basically to limit the number of notes fetched per request.

Look at the existing cursor-based pagination implementation in the note fetching code. Review the linked pull request discussion for context on windowed pagination. Identify where to modify the API to accept start_cursor, end_cursor, or a limit parameter. Test changes to ensure they limit notes fetched per request correctly.
