feat(scheduler): admin run-now/run-all triggers + live progress + completion notices

Add per-job "Run now" buttons and a "Start all now" button to the admin Scheduler
dashboard (admin-gated endpoints). Triggers run the job in a background thread
independent of its interval, refusing a concurrent run (409). While running, the
long jobs (maintenance, enrich, backfill, shorts) report live progress through a
decoupled contextvar sink, shown as a progress bar on the job row via the existing
4s poll. A manually-triggered run posts a completion notification to the triggering
admin's inbox (scheduled runs stay silent to avoid spam); the inbox renders the
"scheduler" type trilingually from type+data. While here, give the maintenance job
its missing dashboard label/description in all three languages.

+"""Lightweight, decoupled progress reporting for long-running scheduler jobs.
+
+A job's work function calls `report(current, total, phase)`; the scheduler binds a sink (via
+`bind()`) that forwards it into the in-memory activity the admin dashboard polls. A contextvar
+holds the sink, so the sync code stays unaware of the scheduler and concurrent jobs (each in
+its own thread/context) never cross wires. When no sink is bound (e.g. a manual sync endpoint),
+`report` is a cheap no-op.
