The shared quick-pay / toggle-paid mutation hooks are now typed: PayableRow for
the row refs, typed mutation payloads, and Dollars for the money amounts (so the
branded type flows through — a caller must supply branded dollars). Strict catch
clauses narrowed via an errMessage(unknown) helper. typecheck + lint (react-hooks
now enforced on this .ts) + build + 48 tests green.

Toggle paid/unpaid was duplicated across the desktop and mobile rows (optimistic
flip + Undo/paid toasts + refresh). Extracted into a shared useTogglePaid()
React Query mutation hook: the caller keeps the instant local optimistic flip,
the hook rolls it back on error and invalidates the tracker/badge caches on
settle. isPending replaces the desktop row's local loading state (badge spinner
+ un-pay confirm dialog). With useQuickPay (P3), both core Tracker write actions
are now idiomatic useMutation hooks living in one place.

Quick-pay was duplicated verbatim in TrackerRow and MobileTrackerRow (create
payment + Undo toast + refresh, with a manual busy flag on mobile). Extracted
into a shared useQuickPay() React Query mutation hook: isPending comes for free
(replaces the quickPaySaving state), the tracker/badge caches invalidate on
settle, and the flow lives in one place. Behavior identical.
(togglePaid keeps its local optimistic flip as-is; other mutations can adopt the
same useMutation pattern incrementally.)
