feat(ui): render the CCTV panel's buttons, CAL chip and meta line from a store

CctvControls presents the switch, navigation and toggle buttons, the CAL
chip and the meta line with a pure presentCctvPanel() and publishes them
to the gev-cctv store; CctvPanel renders them. The controls keep their
listeners on the same elements, and still write the picker, frame, source
badge, calibration readout and summary, which carry no bindings.

A page that imports ui/cctv with its own markup no longer has these
elements painted for it, as with Street Level.
