* wip making it wasm-compatible [again]

* refactored 'GatewaySetup'

* clippy and friends

* removed debug code

* rust 1.72 lints

* ensuring local gateway is available + some comments

* correctly putting network requester data in the same underlying details struct

* improved gateway errors

* changed 'network_requester_config' deserialization

* missing clap annotation for 'enabled' flag in 'setup-network-requester' command
