Extract dashboard_action from shared nested documentable spec to system specs

Removed 'documentable_path_arguments' and 'management'
parameters because they are not used by dashboard_action.

Also moved and renamed the 'documentable_fill_new_valid_dashboard_action' method
from the common actions helper to this file, since it is now only used here.

Hardcoded 'path', 'submit_button_text', and 'notice_text' for dashboard_action.
These remain fixed for now until dynamic values are required in future commits.
