Health: learn n_ctx and total_slots from /props

Implemented /props learning in internal/health/health.go (added Status.NCtx/Status.Slots, PerSlotCtx, and a best-effort GET <base>/props appended to the poll after /v1/models; 0/unknown on any failure without failing the poll) and exposed them in internal/admin/admin.go HostView. Copied internal/health/props_test.go and the replacement internal/proxy/helpers_test.go byte-identical to docs/plans/v2/_files/. Implemented-By: OpenCode session (model recorded in docs/implementer-log.md)
