WBL Opportunities - Allow for more employer details and better multi-user/contact management of employer accounts

For instance, each employer should be able to define one or more admin users that can manage the account. They should also be able to add additional contacts (with all the data stored for each record matching options in Jobready for syncing). These contacts may not need admin access or even any type of user account in WBL Opps.

The employer record itself should also be updated to include fields for all data stored in Jobready. This should also include a company logo and mission, description, and history that are on the Company Profile in Jobready. This could also be AI-generated by allow the employer to make changes.
