* 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).
