Add machine details modal

[valeriansaliou]

Add a new modal providing real-time advanced information, such as:

• The machine serial number (BootMessage.device_id)
• The firmware mode, eg. production (BootMessage.mode)
• The firmware version (BootMessage.version)
• The current ventilation phase (DataSnapshot.phase)
• The current valve positions (DataSnapshot.blower_valve_position + DataSnapshot.patient_valve_position)
• The current blower RPM (DataSnapshot.blower_rpm)
• The current battery level in V (DataSnapshot.battery_level)
• The number of cycles since the MCU booted (MachineStateSnapshot.cycle)
• The number of milliseconds since the MCU booted (DataSnapshot.systick)

As well, provide some internal information about the UI:

• The UI version and build chain (release or production) used and Git commit hash (if possible)
• The UI uptime

Note that this modal could also be used to:

1. Configure the UI langage, see issue Allow to change locale at runtime & store the last locale used on FS #26
2. View the machine's "odometer", see issue Calculate the number of hours of operation #21

Note that some information might be updated live if the machine is running, eg. the angle of the valves.
