The tab bar retires — boards are the app, settings behind the gear, recency the default order

The boards stack becomes the root screen: Settings moves from its own
tab to a sheet behind a leading gearshape button, the sort pickers trade
their text segments for symbols (hand.draw, textformat.abc, clock) with
the words kept for accessibility, and every list now opens sorted by
most recent change. UI tests re-aimed at the gear button and Done-button
scoping fixed for the sheet-over-sheet nav bars — 4/4 green in the
simulator.
