fix(schedules): let the banner see the baseline move under it

`hasDraft` compares the form to the deployed baseline, and that baseline is a
plain value on purpose — made reactive, the sync's effects track every field and
a reset provokes a write that races its own delete. So a toggle that landed
fixed the baseline where nothing was watching, and the drawer kept offering to
discard changes it had already deployed until some other field moved.

The baseline stays plain; a counter beside it marks when it moves, and the
`deployed()` the banner reads depends on that. Bumped where the baseline is
captured, adopted after a save, corrected after a toggle, and cleared.
