GET /api/ee/content-diagnostics/slow

List slow findings - the latest valid slow finding per entity, permission-filtered for the current user. Each item is a flat identity + a top-level duration_ms + a nested details. details varies by entity_type: leaves (card/transform) freeze threshold_ms; containers (dashboard/document) carry the hydrated slow_entities culprit cards. Card items also carry a top-level card_type (question|model|metric) - card findings only, denormalized at scan time. Paginated via limit/offset; total is the full valid count.

Params: include-personal-collections (default false) - when false, entities currently in a personal collection are excluded and personal-collection culprit cards are omitted from slow_entities. entity-types (repeatable, omitted = all) narrows the flagged entity by type; the card sub-kinds are valid values, and card means any card type. Containers rolled up from slow cards are matched on their own type. min-duration-ms (positive int) keeps findings whose duration_ms is at least that (containers filter on their representative duration). query case-insensitively substring-matches the entity name. sort-column (detected-at|entity-type|name|created-at|created-by|collection-name| duration-ms, default detected-at) + sort-direction (asc|desc, default asc); id is the stable tiebreak.
