ui: remove per-row Лог/⟳/✕ buttons from camera table, fix row height to 22px

The camera table actions column (log/restart/delete buttons) is removed:
the table drops to 8 columns across thead, filled rows, empty slots and the
bulk-edit rows. The now-orphaned log subrow and openLogs tracking are gone.
Camera rows get a hard fixed height of 22px via a new table.cams.cams-fixed
rule (zero vertical padding, 22px line-height) so rows never inflate.
