feat: add bypass list, bypass local addresses and username/password to proxy setting (#1059)

* fix: use fs/promises for settings

This PR switches from synchronous operations with the 'fs' module to asynchronous operations with
the 'fs/promises' module. It also corrects a small error with hostname migration.

* fix: add missing merge function of default and current config

* feat: add bypass list, bypass local addresses and username/password to proxy setting

This PR adds more options to the proxy setting, like username/password authentication, bypass list
of domains and bypass local addresses. The UX is taken from *arrs.

* fix: add error handling for proxy creating

* fix: remove logs
