[FL-1723, FL-1662, FL-1870] NFC bug fixes (#745)
* nfc: fix notifications in read EMV sequence
* nfc: set focus on previously saved card
* nfc: add incorrect file format message
* mifare ultralight: increase size of max dump
* elements: draw multiline text only until it fits screen
* nfc: support variable PAN number length
* nfc: change AID display
* nfc: change worker custom event to prevent scene reenter
* nfc: double check for PAN tag
* nfc: fix edit card name appearance
* Nfc: read EMV card without name if PDOL is present.
* Desktop: increase unlock key press interval, switch to OS ticks instead of HAL.
* Desktop: remove debug logging
