chore(maestro): drop dead maestro-names crate

Nothing in the workspace depended on it — session handles are generated
client-side in web/src/names.ts, which carried its own copy of the
wordlists. Also drops two unused deps: rust-embed (no crate used it;
maestro-web embeds via include_dir) and urlencoding in maestro-cli.
