FhirValidator slowing down saving of questionnaires in debug mode

[Rkareko]

Describe the feature request.
Enhance FHIR Resource validation to ensure that it does not block saving of resources during extraction on questionnaire submission.

Additional context
Validation of extracted resources kicks in while saving resources on Questionnaire submission in debug mode which seems to slow down the app.
Saving Questionnaires without the validation takes around 1 - 2 seconds. With validation turned on this shoots up to around 30 - 40 seconds.

This was tested on a Samsung A51 with 4GB RAM running android 13.

Acceptance criteria
Saving of questionnaires with validation should take almost the same time as without validation.

Area path
A list of ordered steps in the app on usage of the feature to support anyone testing it e.g. Code reviewer, QA e.g.

1. Login to the app
2. Fill and save any questionnaire
3. Observe the time taken to complete the questionnaire submission

Implementation plan (For Engineers)
The plan for implementing the solution e.g. via a description or a check list for the various ordered tasks that will need to be completed.
i.e. Describe how you intend to solve the problem

This is a good flag. That's definitely annoying during debug
