Ruben Fiszel 0c204b69bd fix: optimize slow list_assets query for recents loading (#8103)
* fix: optimize slow list_assets query with covering index and v2_job join fix

Add a covering index on asset(workspace_id, path, kind, created_at DESC, id DESC)
with INCLUDE(usage_kind, usage_path) to enable index-only scans for the CTE aggregation.
Fix v2_job join to cast asset.usage_path::uuid instead of job.id::text, allowing
PostgreSQL to use the job_pkey primary key index instead of seq scanning the entire table.

* fix: drop redundant asset indexes subsumed by new covering index

idx_asset_workspace_created_id and idx_asset_kind_path are fully covered
by the new idx_asset_ws_path_kind_recent + the primary key. Verified all
asset table queries still have optimal index coverage. Reduces write
amplification on inserts.
