ShiftPocket

Adds weekly summaries and net hourly pay, plus edit, undo and an on-screen export, without changing the saved data shape.

Adds tips and categorized expenses, and keeps shifts already on the phone when the saved shape changes.

Rebuilds the app so a logged shift actually saves, the form closes, totals update, and buttons are large enough to tap.

First version: log delivery shifts with date, deliveries, gross income in HKD and hours, and see running totals saved on this phone.
