Add Grant section to Profile menu

[estyxx]

The Grant link is missing in the Profile menu on the PyCon Italia website. Currently, users have to go to pycon.it/grants to check if they have submitted a grant and to edit it. This is inconvenient and not user-friendly.

To-Do:

• Add a Grant section to the Profile menu for easy access.
• Ensure the Grant section link is always visible.
• Display messages in the Grant section based on the grant application status:
  • If the application period is open: "Do you need funds for attending the conference? Apply here."
  • If the application period is closed: "The grant application deadline has passed."
• After users submit a grant, update the confirmation message to inform them they can view and edit their grant in their profile.
