feat: show briefed checkmark next to volunteer type tag for accompanying volunteers

[need4deed]

Description

For volunteers whose type is Accompanying or Regular & Accompanying, show a checkmark (✓) icon right-aligned next to their volunteer type tag — but only if they have been marked as briefed in the communication section of their volunteer profile.

Where it should appear

All three places where volunteer type is displayed:

1. Volunteer profile header — upper section of the volunteer profile page
2. Volunteer search cards — in the volunteer list/search view
3. Volunteer section on opportunity cards — where volunteers are listed under an opportunity

Behaviour

• Only shown for Accompanying and Regular & Accompanying volunteer types (not Regular or Events)
• Only shown if the volunteer is marked as briefed in the communication section
• The ✓ icon sits directly to the right of the volunteer type tag
• No icon shown if not briefed

Notes

• The "briefed" flag already exists in the communication section — implementor needs to identify the field/value used there and read it in the three display locations above
