Fix keyborad focus staying true

[xkello]

Description

On Android, confirming a value in certain text fields and closing the drawer could freeze the app and leave the screen only partially rendered. It showed up in a few places: changing the server during setup, GPS settings (antenna height, network provider), closing an account, and saving a feature form. The cause is that the text field still has active keyboard focus when the drawer starts closing, which leaves Qt's Android text input handling in a bad state.

What changed

Each affected drawer now clears focus from its text field(s) in onAboutToHide, right before the drawer starts closing, instead of leaving it until after.

Updated MMLoginPage.qml (change server drawer), MMSettingsInput.qml (shared settings text input drawer, also used by GPS antenna height and accuracy tolerance), MMNetworkProviderDrawer.qml (IP/port/nickname drawer), MMCloseAccountDialog.qml (close account confirmation), and MMFormController.qml (feature form drawer).

Behavior

Before, confirming or closing one of these drawers on Android could leave the screen half rendered and unresponsive until you tapped another field, or in the feature form case, force a full app restart.

After, focus is dropped before the drawer starts hiding, so the screen redraws properly on its own.
