Mobile profile page already has this action, but the desktop chrome had
no way for a seller or staff member to jump into a store they manage —
they'd have to type the URL. Add a compact "فروشگاه من" pill in the
header action row, gated on useMyStores() so it only renders for users
who actually manage a store. Selection mirrors the mobile flow: owned
first, then the first store they staff.
