Explore OpenMeet groups API as community source for polls

[zhiganov]

Discovery

OpenMeet has a full group management system with "Groups you organize" and "Groups you're part of" on their dashboard. Their API has:

• src/group/group.controller.ts — group CRUD endpoints
• src/group-did-follow/ — group membership via ATProto DID follows
• test/group/my-groups.e2e-spec.ts — "my groups" endpoint

Opportunity

Instead of only using our own community config (from scenius-digest/community-admin), Avails could:

1. Fetch user's OpenMeet groups via service auth — show them as communities to scope polls to
2. Create polls scoped to OpenMeet groups — members of the group see the poll
3. Sync community-admin ↔ OpenMeet groups — communities registered in one system appear in both

This would mean users who already have OpenMeet groups don't need to re-register them in community-admin. The group concept is shared across the ATProto ecosystem.
