Removed headers filter from loopbackApi

[Junjiequan]

Description

For better compatibility, visibility, and ease of use headers filter are removed and will no longer be supported by scicat backend

Motivation

Couple of reasons to remove header filters as following:

• Limited Visibility and Debugging: Headers are less visible than query parameters or request bodies, complicating debugging and logging.
• Convention and Consistency: In RESTful APIs, headers are conventionally used for control-related metadata like content type or authentication, not for business logic like filter parameters. Using them for filters goes against standard practices.
• Security Concerns: Using headers for business logic can expose APIs to overlooked security vulnerabilities.

For E2E test to pass, #1328 needs to be merged

looks good to me

But I'd like feedback from facilities that run SciCat in production: @minottic , @dapvan , @dylanmcreynolds

[dylanmcreynolds]

Is this code part of the autogenerated code? We have been discussing regenerating based on the new backend, in which case this PR would be removed, yes?

[minottic]

I am pretty sure our ingestors use for historical reasons the headers in many places rather than the query params. Could the BE change wait until all facilities have rollout the new be, or at least a couple of weeks after the JOBs migration will be over? In the end all the concerns for the moment could be overcome simply by not using the headers. Happy, otherwise, to change the FE

Hmm, as this does not remove the header support in the backend, this change should not affect ingesters running standalone. Only if a proxy does header injection (e.g. for sec. reasons) it could affect the frontend.

I think this is a good point to discuss for the meeting.

[minottic]

yes, indeed. I have nothing against changing the FE, but the PR description mentions a change in the BE

[Junjiequan]

A PR SciCatProject/scicat-backend-next#911 in the new BE removed header filter usage(in datasets, policies, and user-identities controllers).
If some facilities are still using header filters to send requests in datasets, policies and user identities endpoints, then I will make the change postponed

[minottic]

ah ok, thanks, I must have missed that. I support Bjorn's point, let's discuss it in the meeting if time allows
