fluidbased PageLayoutView doesn't take `tables_modify` into account
If a user has not set `tables_modify` for `tt_content` he still gets all the action buttons and translate options displayed.
Clicking on one of this buttons leads to infinity load of the frame.
Some checks are needed to prevent this behaviour.
Steps to reproduce
- Create a backend user and a backend user group.
- Allow the user group to modify pages and also allow listing but not modifying of tt_content
- Open the page module => All options like hide, delete, edit and translate are still shown
