Changing listen/dht port changes the listening/dht ports.

Replace protocol.encryption.set bitmask flags with
protocol.encryption.handshake.set and protocol.encryption.stream.set.
Add encryption_config to map commands to libtorrent EncryptionPolicy.
Startup default matches the old preset (allow_incoming, enable_retry,
prefer_plaintext → handshake=allow, stream=allow).

Update docs and examples. Peer list distinguishes RC4 (R/L),
handshake-only (H/h), and plain (r/l). Fix ui encrypted column
conditional. Add encryption config tests; remove OPTION_ENCRYPTION
parse tests. Drop the encryption command redirect.
