Rework the Apple Watch progress flow

Watch root lists every in-progress workout; picking an exercise runs a paged Ready -> work/rest -> Finish flow (One More + auto-firing Done), with a phase-dot row and brand-tinted count-up/down timers. Includes the configurable rest and auto-finish settings synced over WatchConnectivity and the wrist-down timer fix.
