Remove vote service initialization and route registration from the AppView server. Vote endpoints are no longer exposed. Changes: - Remove votes package import - Remove voteService initialization - Remove RegisterVoteRoutes() call - Add documentation comment explaining removal The vote repository is still initialized for Jetstream consumer use, but no service layer or XRPC endpoints exist. Vote operations flow: 1. Client → PDS (com.atproto.repo.createRecord) 2. PDS → Jetstream (firehose event) 3. Jetstream → AppView consumer (indexing) 4. AppView DB (aggregated vote counts)
