Replace orientation <select> dropdown on setup/configure with the same
visual two-button picker used in the SPA (SVG frame diagrams, ribbon
indicator, active highlight). Hidden input carries the value on submit.

Firmware: normal_operation() now calls show_setup_qr(mac) on 404 instead
of epd_fill(COLOR_RED) — device shows scannable QR with its own MAC when
not yet registered.
