rzen c05e83cff7 Queue document writes durably and surface sync trouble in the UI
iCloud Drive writes now flow through a persistent WriteBacklog sidecar
(drained with backoff, flushed on backgrounding, wiped with the cache on
account change), so a save can never be lost to a transient coordinator
error. A status banner on the workout list surfaces stuck syncing.
Also: the split picker gains a Recent section with day labels, split
rows fold SplitItem into SplitListView, and list rows dim the multiply
sign in sets-by-reps.
