Move Rack: rack name in title via getter, tag chips, batches list
(read-only), Type + To Node + To Station picker. Atomic Save commits
all batches via /fp/tablet/move_rack/commit.
Stop Timer: opens with state already at 'stopped' (server flipped on
load via /labor_timer/stop), pre-fills billed_* from accrued.
Operator edits → Save (state → reconciled).
Save & Start New Timer chains into a fresh timer for the same step
via the start_new=True flag — mirrors screen 10's right-most button.
