refactor(db): port sleep/wake sweeper to sqlc

Tranche 7 — all 11 raw sites in sleeper.go. Adds sleep_enabled and
sleep_idle_minutes to schema.sql and three runtime.sql queries:
ListSleepCandidates, GetServiceDomainText, GetServiceStatusText. Status
writes reuse SetServiceStatus; the wake loader reuses
GetServiceRuntimeWithOwner (the projects join is FK-safe).

Also drops a dead port read in handleServiceSleep that was loaded but
never used.

TestRuntimeLiveInvariants now covers the sweep filter and both text
lookups on live Postgres.
