[FL-1178] Idle screen improvements (#444)

* Dolphin idle screen: Cleanup of debug views; Hold [down] to open debug view; Sequential input for unlocking;
* Lock screen popup, WIP
* Fix reverse modulus
* Lock popup added
* Dolphin: timer for handling UI animation sequences
* Allow tick events to be discarded on queue overflow and prevent timer service from crash
