UI & Functionality - Warning modal before filing COA

[sienna-oldaccountdontuse]

Description:

This ticket is to implement the UI AND Functionality. We need a modal to warn users before the file a COA, because if they file one, it will be effective at 00:01 the next day, which means they cannot file anything else for the rest of that day. In this modal, they can "cancel" (which will leave them on dashboard) or "File Change of Address" (which will go into a COA filing).

Acceptance Criteria

• Given I am logged in as a BCorp, when I click "Change" on the address component, then i will see a modal appear.
• User can select "Return to dashboard" in the modal to go back to the dashboard
• ~User can click outside the modal to go back to the dashboard~
• User can click "Continue to Change of Address" to go into the filing flow

• ~User can click outside the modal to go back to the dashboard~ removed because @sienna-freshworks added unnecessary details in the ticket

Works fine. (Although the designs are not updated as per implementation : https://projects.invisionapp.com/d/main/default/?origin=v7#/console/18216776/388387098/preview?scrollOffset=1888.75 ) discussed with @cameron-freshworks and @sienna-freshworks

Implementation

Moving it to Done.
