FL-53: new NFC worker, A/B/F/V poll and display. (#283)

* GUI: view. Flooper-blooper fix compilation error.
* GUI: view and viewdispatcher bones
* GUI: view implementation, view models, view dispatcher
* GUI: view navigation, model refinement. Power: use view, view dispatcher.

* HAL Flash: proper page write. Dolphin: views. Power: views

* Dolphin: transition idle scree to Views
* Dolphin: input events on stats view. Format sources.

* HAL: flash erase. Dolphin: permanent state storage.

* Dolphin: first start welcome. HAL: flash operation status, errata 2.2.9 crutch.

* NFC: rewrite worker
* NFC: add support for B,F,V.
* NFC: replace rfal irq hanlder with realtime thread, more details about cards.

* Bootloader: LSE and RTS shenanigans, LED control, morse code for LSE failure error.

* F4: stop in Error_Handler

* BLE: handle working FUS, but empty radio stack.

* HAL: alive FUS is now sufficient for flash controller access

* Dolphin: update model after state load

* NFC: detect navigation

* RFAL: use osPriorityISR for isr thread

* NFC: emulation

* Bootloader: rollback incorrectly merged rename

* Dolphin: rollback incorrectly merged changes

* RFAL: remove volatile from thread attr

* RFAL: do not call platform ErrorHandler, error codes is enough

* NFC: improved error handling

* Format sources

* NFC: reset detect view model on start

* Format sources

* update codeowners

* NFC: hide last info if no card detected
