The schedules table builds a column per target, including agents that
have since been destroyed (their past schedules linger). Those columns
showed identically to live agents, so the operator couldn't tell a
schedule still targets something that no longer exists.
Flag them: renderSchedulesTableHead now checks each agent column against
the live roster (containersState) and, for any that isn't there (and
isn't 'operator', which is always valid), greys + strikes through the
column label and titles it 'no longer exists (gone)'. The rows stay
visible + cancellable — the operator can see the stale targets and clear
them rather than be surprised by phantom columns. Build green.
Largest step of the tabs.js split: the SCH3DUL3S tab — reminders +
scheduled-prompts (the lists, inline create row, per-row edit form, and
fire-now / cancel actions) — moves into a new schedules.js, ~1060 lines
out of tabs.js. It owns its own module state (schedules list +
edit-in-progress tracking) and reads the shared agent roster from
state.js for the target-chip pickers; render + format helpers come from
util.js, so the keystones (state.js, util.js) paid off here.
Exports the four entry-wired functions — applySchedulesChanged /
applyRemindersChanged (mutation dispatch), refreshSchedules /
refreshReminders (tab activation + cold-load) — plus activeScheduleCount
(the count pill). The 19 other functions stay module-private. Also drops
the now-unused paintAtomic import from tabs.js (its only callers were in
this block).
Behaviour-preserving code motion; esbuild inlines schedules.js into the
tabs.js bundle. Build green; tabs.js drops ~1060 lines (4323 → 2969).
