Create an on-device recovery updater application for Flipper OS

[alchark]

• Discover the running board type
• Enumerate local storage supported by the RK3576 boot ROM (UFS, eMMC, SD card)
• Query the image server for available U-Boot images for the board
• Query the image server for available exported profile snapshots
• Search removable storage (SD, USB) for available U-Boot images for the board and/or exported profile snapshots
• Present a minimal TUI to select target storage device for flashing and to choose build versions to flash
• Present a minimal GUI on the Flipper One screen to select target storage device for flashing and to choose build versions to flash
• Run the installation (blkdiscard, create GPT, create Btrfs with subvolumes structure, receive selected profiles from snapshots, install kernels for each)

I believe this needs to be a statically linked binary application to minimize dependencies for use in an initramfs.

@Yury-MonZon let's brainstorm the implementation
