scope=all was issuing 1+2N DB queries (1 count + 2 agent-name lookups
per session). scope=mine was issuing 2N queries (1 user-count + 1 total
per session). Both are now replaced with 3-4 bulk queries total,
regardless of session count.
Affected endpoint: GET /api/agents/{id}/sessions?scope=all|mine
