Adds flash_mcus.sh — a Bash tool for flashing Klipper firmware to all supported Blocks printer MCUs. Supports an interactive TUI, --list-json for JSON output, --flash / --flash-all for headless use, and --force to bypass version checks. Flash methods: CAN via Katapult, USB Katapult, BOOTSEL/picoboot, STM32 DFU. UUID auto-discovery from printer.cfg; live firmware version query from Moonraker API; auto-starts Klipper/Moonraker if stopped. Bundles mcu_config/ files for EBB CAN (STM32G0B1), Eddy Duo (RP2040), and Octopus (STM32H723) with their Katapult bootloader counterparts. Adds curl and jq to system-dependencies.json (required by flash_mcus.sh).

Flashing Klipper firmware to the printer's MCUs (Octopus Pro, EBB-36 toolhead, Eddy Duo probe) has historically been a fully manual process: building firmware with make menuconfig, determining the right flash transport for each board (CAN via Katapult, STM32 DFU, RP2040 BOOTSEL), looking up CAN UUIDs from printer.cfg, and invoking the right tool in the right order with the added constraint that the CAN bridge MCU (Octopus) must be flashed last or it drops can0 mid-session.
This is error-prone, time-consuming, and a significant source of friction during printer firmware updates. It also blocks building a future GUI panel in BlocksScreen: the UI needs a way to discover MCU state (detected, current version, needs update) and trigger flashing without re-implementing all of this logic in Python.
