refactor: delete signet-db, signet-node-types, and signet-rpc

These crates are fully replaced by signet-storage, signet-hot, and
signet-rpc-storage respectively. Remove 6,700+ lines of dead code and
clean up 22 unused workspace dependencies.

Replace reth-db tempdir_path with tempfile in signet-node-config.
