refactor(inbounds): drop the single-user shadowsocks inbound paths

isSSMultiUser treated 2022-blake3-chacha20-poly1305 as a single-user
inbound, and the inbounds page grew a row QR modal, a separate link
panel in the info modal and a client-count skip for that case. The
method is no longer allowed on inbounds, so every shadowsocks inbound
carries clients and those paths cannot be reached: remove them along
with the inbound-level QrCodeModal they alone opened.
