Updated the backend services and handlers to properly detect and pass
the has_cover parameter's validity state to the database layer.
Changes:
- services/search.go: Changed HasCover type from bool to pgtype.Bool
to support 3-state logic (NULL, TRUE, FALSE)
- handlers/media.go: Fixed 3-state detection by checking if has_cover
exists in query params before setting Valid flag
- router/search.go: Fixed 3-state detection to match media.go logic
- router/frontend.go: Use pgtype.Bool{Valid: false} for SSR initial
load to ensure no filtering occurs on first page load
The key fix is detecting whether the has_cover parameter was actually
sent in the request:
- Parameter not sent → pgtype.Bool{Bool: false, Valid: false}
- Parameter sent as "true" → pgtype.Bool{Bool: true, Valid: true}
- Parameter sent as "false" → pgtype.Bool{Bool: false, Valid: true}
Previously, media.go was hardcoding Valid: true, which meant it was
always filtering by has_cover=false (only books without covers) when
the parameter wasn't sent, causing searches to incorrectly return
0 results for queries like "1984".
This ensures consistency between the JSON API endpoint (media.go) and
the HTML endpoint (search.go), and fixes the critical bug where SSR
was returning 0 books on initial page load.
