List every photo's open Enhance jobs for a jobs manager

GET /enhance/jobs without a path now answers the jobs manager (FVR #99):
every photo's queued / running / unavailable jobs, plus ready / failed /
expired ones touched in the last 3 days, newest first, discarded and
approved hidden, at most 100. DB only; the poller keeps rows current.
An optional status=a,b filter applies to both forms.
