Add Proxy-Screen

[zeitschlag]

• Advanced Settings gained a new entry (Proxy) under Server. This settings lives behind the Passcode/Biometrics-protection.
• Adds a new screen to see, add, and delete proxy-servers (Swipe to delete only works on device, not in the simulator, but trust me, it's there!). Looks like this:

Screenshots

• Code follows the Android-implementation, I didn't reinvent the wheel

very nice! 👍 i did not yet manage to fine a today working proxy (cc @adbenitez do you have one :), some nitpicking below, and some comments on the UI:

1. the "connecting..." and connected information are missing, afaik, there is no special "proxy connectivity", but android just repeats what is otherwise written beside "connectivity" (so the "global state"), however, this is an important information to have in that dialog when testing out if a proxy works

2. the "protocol" should not just be a string, let's put that into a square box as on android, we can use the same style as

3. when there are no proxies, android does not disable the switch, but allows to turn it on and shows the "Add Proxy" dialog - i think, this is a bit more user friendly EDIT: it is fine as is

point 1. seems quite important, i would add that to this pr, so the user gets some some feedback, otherwise one is quite blind. also, disabling owner-verification should go to this PR

the other points can also come later, the dialog is also a huge things without 2.+3. - and there are more things to do for proxy beside polishing :)

yeah, it starts working :)

first times, we have a proxy connection on iOS :)

a bug i encountered during testing:

• add a proxy, tap a second time to activate (that should not be needed, added proxies should become automatically the active one)
  -> the proxy is shown twice in the list

usability-wise, in general, a simple tap on a proxy can start using the proxy already. no need for a confirmation. things are easily undoable.

both are shown issues are shown in the following video:

with the "not-disable-switch but show add-screen" i mentioned on first review: we can leave things as is, the "add proxy" is easy enough, even though it is different on android
