Show full group membership for members (hover tooltip + optional member profile)

In Members → search by name, we only see the first few groups someone belongs to.
There’s no way to view the full group list without downloading an export.

Feature request

Option A (quick win):

• Add a hover tooltip on the +X indicator

• Tooltip shows the full list of groups the member belongs to

Option B (bigger enhancement):

• Click a member name to open a member profile view

• Profile shows:

  • List of group/s the user is a member of

  • Current and/or former roles (ex: co-chair)

Why this matters

• Faster admin workflow (no exports just to check group membership)

• Helps understand member participation + leadership at a glance
