feat(communities): add update handler and XRPC endpoint master

Implements social.coves.community.update endpoint for updating community profiles (displayName, description, visibility, etc.). Changes: - Add UpdateHandler with XRPC endpoint support - Register update route in community routes - Uses community's own PDS credentials (V2 architecture) - Preserves OAuth TODO for production deployment Related: Update endpoint was defined in service layer but had no HTTP handler or route registration. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
