[front] Split query to fetch agent_configurations

[tdraier]

Description

followup #8050

Retrieving all assistants is very slow because of a complex query plan, due to an "or" in the query. Splitting in 2 queries which only have an index scan may be more efficient (especially in terms of memory)

Current query :

EXPLAIN SELECT * FROM "agent_configurations" AS "agent_configuration"
WHERE
  ("agent_configuration"."scope" in ('workspace', 'published')
    OR "agent_configuration"."authorId" = 6334)
  AND "agent_configuration"."workspaceId" = 4525
  AND "agent_configuration"."status" = 'active'

QUERY PLAN
Bitmap Heap Scan on agent_configurations agent_configuration (cost=22.22..322.72 rows=77 width=802)
Recheck Cond: ((("workspaceId" = 4525) AND ((scope)::text = ANY ('{workspace,published}'::text[])) AND ((status)::text = 'active'::text)) OR (("workspaceId" = 4525) AND ("authorId" = 6334) AND ((status)::text = 'active'::text)))
-> BitmapOr (cost=22.22..22.22 rows=77 width=0)
-> Bitmap Index Scan on partial_agent_config_active (cost=0.00..9.33 rows=77 width=0)
Index Cond: (("workspaceId" = 4525) AND ((scope)::text = ANY ('{workspace,published}'::text[])))
-> Bitmap Index Scan on partial_agent_config_active (cost=0.00..12.86 rows=1 width=0)
Index Cond: (("workspaceId" = 4525) AND ("authorId" = 6334))

Replacing with :

EXPLAIN SELECT * FROM "agent_configurations" AS "agent_configuration"
WHERE
  "agent_configuration"."scope" = 'private'
  AND "agent_configuration"."authorId" = 6334
  AND "agent_configuration"."workspaceId" = 4525
  AND "agent_configuration"."status" = 'active'
  
QUERY PLAN
Index Scan using partial_agent_config_active on agent_configurations agent_configuration (cost=0.29..8.31 rows=1 width=799)
Index Cond: (("workspaceId" = 4525) AND ((scope)::text = 'private'::text) AND ("authorId" = 6334))

And :

EXPLAIN SELECT * FROM "agent_configurations" AS "agent_configuration"
WHERE
  "agent_configuration"."scope" in ('workspace', 'published')
  AND "agent_configuration"."workspaceId" = 4525
  AND "agent_configuration"."status" = 'active'

QUERY PLAN
Index Scan using partial_agent_config_active on agent_configurations agent_configuration (cost=0.29..317.96 rows=79 width=799)
Index Cond: (("workspaceId" = 4525) AND ((scope)::text = ANY ('{workspace,published}'::text[])))

Total planning and execution time is smaller, but more importantly we only do index scans.

Risk

List of assistants different (order ? )
