fix: Complete schema adaptation for all tool modules

- auth.ts: Use suspendedAt instead of isSuspended, role instead of isAdmin
- comments.ts: Use role='admin' for admin user queries
- documents.ts: Use suspendedAt IS NULL for active users
- events.ts: Return actorRole instead of actorIsAdmin
- shares.ts: Use role='admin' for admin user queries

All queries validated against Outline v0.78 schema (10/10 tests pass).
