This commit removes support for the deprecated EncodingSortedZlib format (type 1) which was dropped from the BOLT 7 specification. All zlib compression and decompression logic has been removed from lnwire messages. The EncodingSortedZlib constant is now marked as Deprecated to retain protocol documentation. The decode path now explicitly returns an error when a peer attempts to send zlib-encoded data, rather than a generic unknown encoding error. All tests that previously verified zlib scenarios have been cleaned up or deleted. This removal is safe because lnd has never sent zlib-encoded data, and nobody on the network sends type 1. Additionally, dropping this encoding removes the package-global zlibDecodeMtx, improving performance and security without introducing new DoS vectors, as receiving type 1 now simply triggers an instant disconnect.
