Reviewer Notes & GitHub Profile Fix

New Features

Reviewer Notes on Applications: Admins and mentors can now add shared review notes on individual mentee applications. Notes open in an inline popover for quick editing, helping reviewers track assessments across large applicant pools.
Markdown Rendering: Program descriptions now correctly decode and render markdown content, ensuring headings, lists, and formatting display as intended across the platform.
UTC Date Tooltips: Application and due date fields now display tooltips clarifying that all times are in UTC, reducing timezone confusion for applicants worldwide.

GitHub Profile Submission Error: Fixes an issue where linking a GitHub account already associated with another LFX user caused the profile submission to stall with no feedback. Users now receive a clear error message when a conflict is detected, allowing them to take corrective action.
