Add Parachain status check to pre-flight

[gianfra-t]

Description and potential addition

Recently an off-ramp failed at the RequestRedeem stage due to the Oracle being offline, and the redeem extrinsic failing with security.ParachainNotRunning. Furthermore, since the extrinsic was executed but failed, there is no way to recover these funds by re-executing it again.

This can actually be checked on initialization of the app (or in the backend and append to the status), and avoid starting off-ramps that will fail for certain.

Hey team! Please add your planning poker estimate with Zenhub @ebma @gianfra-t @Sharqiewicz

@vadaynujra should we priortize this, i consider this important as failing check would fail the offramp?

[ebma]

Please do, I also think it's important.

[vadaynujra]

@prayagd makes sense to prioritise this one given the low effort. Could you also confirm (preferably with a screenshot), what the user would see if the checks fail, today?

[ebma]

@vadaynujra we would just add this to the set of current checks and thus, it would also show the 'Application initialization failed...' error message, without giving any specific hint.

Understood, thanks @ebma

This ticket is depriortized for the current sprint
