feat(ui): render the CCTV calibration readout and its pose editor from the store

presentCctvCalibration() joins the panel view: ADJUST, SAVE CAL, RESET CAL
and the seven pose chips render from the gev-cctv store. The inline editor
is store state: starting an edit publishes its field, starting value and
finish(), and the CctvCalValue chip renders the number input. The draft is
set once on mount so a refresh while typing keeps it; each edit gets its
own input. Commit and cancel rules, the captured base pose and the camera
guards stay with CctvControls.

formField.js had no other user and is removed.
