Schedules list: status (enabled/paused) + cron + source-group tags +
actions (Run-now when enabled+online, Edit, Delete). Run-now reuses
dispatchScheduledJob — same path real cron fires take, so each
referenced source group runs as its own backup with its own tag.
Falls back to a 409 if the agent is offline.
Schedule new/edit form: cron input with five preset chips
(quick-pick @hourly / nightly / 6h / weekly / monthly), source-group
multi-pick rendered as styled checkbox cards (visual state tracks
the underlying box via a tiny inline script), enabled toggle. No
paths/excludes/retention/kind on the schedule itself — those live on
source groups now.
Server-side validation re-renders with the operator's input + ticked
groups intact. Every successful mutation calls pushScheduleSetAsync.
Adds .schd-row, .preset-chip, .picker styles.
Extract header/vitals/sub-tabs into a host_chrome partial that every
host-detail tab page renders. Sources / Schedules / Repo go from
inert divs to real <a> links backed by stub pages that share the
chrome and a 'coming next' body — slices 2/3/4 fill them in.
Also re-establishes the version indicator (host_schedule_version vs
agent's applied_schedule_version) in the header.
Drops the legacy fat-schedule list/edit templates that referenced
fields removed by the P2 redesign (Manual / Paths / RetentionPolicy
on Schedule); the new templates land in slice 3.
