Fix db function calls and add missing functions

- Fix get_activities to use get_activities_paginated
- Add get_user_assets, delete_asset, count_users, count_user_activities
- Add get_user_activities, get_renderer, update_anchor, delete_anchor
- Add record_run and get_run functions
- Fix create_asset calls to use dict parameter
- Fix update_asset call signature
