Enable sharing of request drafts

Description: Enable sharing of request drafts, which is currently not possible in Workfront.

Importance: Requestors save drafts to gather missing information or discuss with managers. Sharing drafts allows for manager input before submission.

Benefits:
• Manager review and feedback.
• Team collaboration.
• Comprehensive review by all parties.

Desired Functionality: Add a "Share draft" icon to share drafts with internal team members.
Current Behavior: Workfront allows sharing request queue links for direct submissions, but drafts remain private until submitted.
