Login error handling

[RA341]

Changes

Added support for autofill so that password managers can autofill credentials.

Ui changes

Default error handling UI.

Specific error messages for certain HTTP codes. If a response does not match a specific code, it defaults to the normal UI.

Added a check for empty inputs.

Bug fix

There was also a bug in the auth logic

The if condition adds a port regardless of the protocol, which will cause a tls mismatch error if we put https address and the error handler adds the port.

relevant line

if (user.serverAdress!.split(":").last != "8096" &&
          user.serverAdress!.split(":").length == 2 

adds a HTTP check

if (user.serverAdress!.split(":").last != "8096" &&
          user.serverAdress!.split(":").length == 2 &&
          user.serverAdress!.split(":").first == 'http')

looks great works great. sorry this didn't occur to me earlier, but, jellyfin actually supports empty passwords. for example this branch now prevents jellyflix from accessing the demo server at https://demo.jellyfin.org/stable
