[FEATURE REQUEST] Add warning in http connections

[jesmrec]

When http:// url is set on the login view it's straight approved with no warning to the user. http connections are not secure, and it's relevant that users are warned about that issue.

This is the iOS warning:

This is the Desktop client warning:

@tbsbdr @EParzefall anything you'd recommend? We can also change the existing iOS + Desktop warnings.

My suggestion for all clients:

Insecure HTTP URL The URL you provided uses HTTP rather than the encrypted HTTPS protocol. If you continue, your communication will not be encrypted.

For consistency reasons all affirmative buttons should be labeled "Continue".

Hi @rohnsha0! As it's already been some time since you don't reply, we have just assigned this issue to a member of the team, we would like to have this in our next release. In any case, feel free to work in any other non-assigned issue of our backlog! Thanks a lot 😃
