Fix camera calibration card contents completely vanishing during calibration

[Gold856]

Description

Per #1972 (comment), camera calibration got broken because I accidently hid the entire contents of the camera calibration card in #1972. Now, v-show is only applied to the calibration table so that only the calibration table is hidden during calibration.
