Fix: Send raw headers in HTTP response

[hdmunguia]

Raw headers added via addRaw() were not being sent in the response.
The writeHeaders() function only wrote parsed headers from headers.list()
but skipped headers from headers.rawList().

This fix adds a loop to write raw headers after the parsed headers.

Fix: Send raw headers in HTTP response

Problem

Raw headers added via headers().addRaw() were not being sent in HTTP responses.

Root Cause

The writeHeaders() function in src/common/http.cc only wrote parsed headers from headers.list() but skipped
headers from headers.rawList().

Solution

Added a loop to write raw headers after the parsed headers, ensuring all headers (both parsed and raw) are
included in the response.

Thank you for your contribution, @hdmunguia. I'm going to discuss with my peers and we'll get back to you. In the mean time, please remember to bump the patch version.

[Tachi107]

Hi! Could you please add a test case demonstrating the old behaviour, and how your patch fixes it? Thanks!

[hdmunguia]

Test changes pushed. Confirmed test case fails if fix is commented out.

I think you forgot to push those changes, as I don't see the unit test or versioning changes.

[kiplingw]

You're still missing the versioning change previously discussed.

[hdmunguia]

I've updated version.txt and pushed. I hope this is the proper process.

[kiplingw]

Unfortunately still not correct. Please read the documentation linked above since you've updated the implementation without adding or changing any interfaces.
