feat(kit): render the status badges and empty states with UiBadge and UiEmpty

UiBadge takes a tone and carries Core's gev-status-badge class, with
the density variants and colours left to its callers; the CCTV source and
calibration badges and the rail card badges render through it. UiEmpty takes
a title and hint, with the title as the line itself, since Core's
empty states are one line; the Scene shot list, mission roster and imagery
strip use it.
