DEV - Implement new design for grant creation modal

[lyannne]

Description: Implement the new design for the grant edit/grant creation modal. Currently, the modal only shows up when the user tries to create a grant. We want it to show up for both creating and editing a grant.

Current Design:

New Design:

OPTIONAL: Make sure BCAN POC is a dropdown of valid accounts (will involve AWS probably)

Notes:

• Feel free to take creative liberties when necessary! For example, the current design may not be updated to reflect the document part correctly. It should be a name, link, and scope document/supporting resource, like how it functions
• May take longer than 2 weeks!
