feat: critical file hash checks, red status bar for troubleshooting

[tracernz]

Fixes #[issue_no]

Summary of Changes

We have had a lot of trouble with mods tampering with core files like systems.cfg, and breaking our aircraft in subtle ways. This PR adds hashing of a few critical files, and checks in the EFB. If any tampered files are detected the status bar at the top of the EFB changes to a red hue, and the files are listed on the troubleshooting page. The list of critical files is intentionally very small to avoid flooding the troubleshooting page on the EFB and making it useless for other purposes.

It also makes the EFB status bar turn red when any other troubleshooting issue occurs. When the status bar is red, clicking it will take the user to the troubleshooting page.

Testing instructions

With no A32NX or A380X mods installed you should see the case in "all okay" under screenshots above.
Try install a lighting mod from flightsim.to and see if it triggers a mismatch.

From any other page on the EFB, click the status bar when it is red, and make sure it takes you to the status page. Click the back arrows (<- Settings - Troubleshooting) and make sure it takes you back where you came from.
