Add phone number for main Partner contact, alongside email #5660

Summary

Bank Organizations need a top-level contact phone number for Partners.

Why change?

This will make it easier for Bank Organizations to maintain their own contact number for how to call the Partner.

Steps to replicate

• Log in as Bank Organization
• Navigate to Partner Agencies -> All Partners
• Observe that we have email but not phone number
• Click on a Partner, then Edit Details
• Observe that there is an input for email but not phone

Mock-ups of where you can add phone

Criteria for completion / testing needs

• Add new column for partner phone number
• Expose this in the new and edit form for the Partner (as not-required)
• Expose this in the Bank's view of the Partner
• Add it on the list of partners, in the same column as Email (on a new line)
• Update the column header in the list to be "Contact Information"
• Update specs, especially Request Specs, to reflect this change
