* Check for empty headers in import
* Added import permission
* Fixed model path in docblock
* Added import gate to default blade
* Check if the user is an admin OR idf they have import permissions
* Walked back that admin permission
Since admins are bound by full company support, it makes less sense to let admins have this permission by default, versus having them specifically designated to the import permission
* Add Authorizable trait and interface to our user model so we have access to User::can/User::cant. We should take a look at where else our user model has diverged from Larvel since it was created...
* Policy cleanup/fixes.
This commit adds policies for the missing backend/"settings" areas. The
permissions were implemented a while back but the policies did not, so
authorizing actions was failing.
In addition, this condenses a lot of code in the policies into base
classes. Most of the files were identical except for table names, so we
move all of the checks into a base class and override the table name in
each policy.
* Use a better name and permission for the check in the default layout.
