ui: restore ⟳/✕ actions in edit mode only; shrink toggles; uniform 22px rows

The camera table actions column is back as the 9th column but stays empty in
the normal view — restart (⟳) and delete (✕) buttons render only on existing
cameras while bulk-editing. Restart in bulk mode no longer reloads the table
(keeps pending edits); delete reloads as before.

Row height is now truly uniform: cams-fixed cells use line-height:1 with
vertically-centred controls, the Вкл/Запись toggles shrink to 30×16, and
selects/inputs/action buttons cap at 20px so filled rows match empty slots.
