Improve template color settings TCA
These options at the bottom of the "Template" tab can be improved:
The first two options have no effect if the "Full" Template is selected. Since the settings are reloaded on a change of the template selection, these fields could be hidden.
The other four could be explained better:
- Give hint that these are colors for the detail tables (header)
- Put the two row title options on the left, the data cell options on the right to better resemble the frontend structure
