feat(wallets): segmented sort control (like the Receive all/z/t toggle)

Replace the sort dropdown with a material::SegmentedControl — Created / Addresses
/ Txs / Size — matching the Receive tab's address-type toggle, with the asc/desc
arrow beside it. Shorten the four sort labels to fit the segments (updated across
all eight languages + the back-fill script). The direction arrow is positioned
explicitly on the segment's baseline (the control is draw-list based and doesn't
advance the layout cursor).
