feat(app): optimize boards queries

Browse Source 
Use SQL instead of python to retrieve image count, asset count and board cover image.

This reduces the number of SQL queries needed to list all boards. Previously, we did `1 + 2 * board_count` queries::
- 1 query to get the list of board records
- 1 query per board to get its total count
- 1 query per board to get its cover image

Then, on the frontend, we made two additional network requests to get each board's counts:
- 1 request (== 1 SQL query) for image count
- 1 request (== 1 SQL query) for asset count

All of this information is now retrieved in a single SQL query, and provided via single network request.

As part of this change, `BoardRecord` now includes `image_count`, `asset_count` and `cover_image_name`. This makes `BoardDTO` redundant, but removing it is a deeper change...
