Request staff notes: Edit note details

User story:
As a circulation staff person
I sometimes want to capture information and notes about a request
So it can be shared with other internal staff working with the same request

Scenarios:

1. Scenario
   • Given a request note in view mode (completed in UIREQ-459)
   • When Edit button is clicked
   • Then the "Edit note" form should open
     • Header: "Edit: <noteTitle>"
     • "General information" accordion:
       • Record last updated/created component (closed by default)
       • Note type - Dropdown menu containing all note types specified in Settings > Notes
       • Details - Large text area with rich text editing
     • "Assigned" accordion (out of scope for this story - see UIREQ-467)
     • Buttons:
       • Cancel - Closes form without saving changes and returns user to request record
       • Save & close - Saves changes, closes form and returns user to request record
       • X in upper left - Same as cancel
