88facf20c1 nfc: DESFire fixes (#1334)
* nfc: don't give up on reading DESFire card if GET_KEY_SETTINGS fails
  Some cards are configured to refuse to provide key settings, but still
  provide other info.  For example, Ubiquiti UniFi Protect access cards
  won't list keys or applications, but will still answer GET_FREE_MEMORY.
* nfc: don't show error when saving DESFire card with no applications
* nfc: fix DESFire load with 0 applications or no PICC key settings

Kevin WallaceandGitHub d378ca6fda desktop: prompt to power off on back button long press (#1279)
* desktop: prompt to power off on back button long press
   Implemented by launching Power Settings app, passing "off" as arg to
   directly jump to "power off" scene.

9c9f66a30f nfc: add debug PCAP output, refactor Mifare DESFire following #1095 (#1294)
* nfc: refactor nfc_worker_read_mifare_desfire to use furi_hal_nfc_tx_rx
  Renames furi_hal_nfc_exchange_full to furi_hal_nfc_tx_rx_full, and
  rewrites it to use furi_hal_nfc_tx_rx.  This eliminates the final
  remaining use of furi_hal_nfc_exchange, so remove that.
* nfc: write debug.pcap when debug mode enabled
  Limited to NFC protocols that use furi_hal_nfc_tx_rx to communicate.
* switch to Doxygen style comment

4b45746b8e Fix MiFare DESFire GetKeySettings response parsing (#1267)
Only the bottom nybble of buf[1] is the key ID; the top nybble contains flags.
Notably, the top bit is set for AES mode on EV1+ cards, and ORCA cards in the
Seattle area were just upgraded to include an app that uses AES.

Prior to this, cards with flags set could be read and saved just fine, but
loading them would fail due to missing keys.  After this, tags saved with the
old version will load fine, and when re-saved will have the flags separated
out into a new field.

3857cd7d5f Nfc: add basic Mifare DESFire support (#1024)
* Fix TextBox word wrap behavior
* Wrap width is 120 pixels, not 140. (140 is larger than the screen!)
* Glyph width already includes spacing; don't add 1 additional px
* When starting a new line, include wrapped glyph width in new line_width.
* Call canvas_set_font before text_box_insert_endline so that glyph
  width is calculated using correct font.
  Previous approach worked somewhat well using default TextBoxFontText but
  this version is more robust, particularly when using TextBoxFontHex.
* Add basic Mifare DESFire reading, file/app browser
* Fix build with APP_ARCHIVE=0
* Add bool type to flipper_format
* Add ability to save and load DESFire card data
* Skip over NfcSceneDeviceInfo when viewing saved DESFire info
* mf_df_clear: don't leak master key settings key versions
* When opening a DESFire card from Archive, retain UID emulation behavior
* rm unnecessary \r\n
* show Popup instead of leaving view in bad state
* Move NfcReaderRequestData out of union
  This makes it safe to emulate DESFire/EMV without clobbering card data.
* Display saved DESFire cards via NfcSceneDeviceInfo
* Display and save file metadata even when contents are missing
  This can happen when a file doesn't allow unauthenticated reads (see the
  call to mf_df_parse_read_data_response in nfc_worker.c).
