Replaced 'login_as' with 'do_login_for' using 'management: management_section?' to
handle login requirements correctly for each context.
Also removed the now-unused 'documentable_fill_new_valid_budget_investment' helper
from common actions.
Note that it does not seem necessary to create an administrator with the user, as was
done in the original shared example. Also, as in the previous commit, it appears that
we do not need to set the user as the author when creating the documentable.
While reviewing this, we also noticed that the create(:administrator, user: user) call
was unnecessarily included in the nested_imageable system spec in commit cdfaec5217 when
the path is a management section. So we use this commit to remove the unnecessary condition.
Make 'path', 'submit_button_text' and 'notice_text' dynamic based on
the factory.
Also adjusted the user. Budget investments require a level 2 user but do not need to be
an administrator.
Copied and renamed the 'documentable_fill_new_valid_budget_investment' method from
common actions, and introduced a 'fill_in_required_fields' method to manage multiple factories.
Added the two tests that were conditionally skipped in the shared example using
'unless: documentable_factory_name == "dashboard_action"', but omitted the call to
'documentable_redirected_to_resource_show_or_navigate_to', since it only applies to
proposals.
Note that when we create the documentable seems do not need use the user as author.
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.
