Core: RU: revert some strings.xml changes

Apparently I'm an idiot.
Replacing "Yes/No" strings looked like a good idea,
but instead they started to pop in completely unrelated
places. Rather than fixing all AlertDialog parameters,
I think it's better to revert my changes there.
Also reverted some strings with replaced quotation marks.
I never saw these strings used in the UI, so this helps
keep the file "cleaner".

Keyguard: do not show maximized on simpin and several fixes

- to show a maximzed widget container on first boot when simpin
  or puk is requested does not make any sense. In this case
  show it as normal view
- fix sometimes unresponsive unlock handle on maximized widgets
  and bring it to front (happened only in combination with
  lock before unlock)
- a bit codecleanup and centralize
- fix animation was visible on screnn turn on. Now it is directly
  maximized visible
