In native raw stack trace image list, render code id instead of debug id?

When downloading a raw stack trace with image list (currently only possible when looking at unsymbolicated stack trace, covered in https://github.com/getsentry/team-ingest/issues/686), the ID rendered for the debug files is the debug id: https://github.com/getsentry/sentry/blob/5cbbe2e849e594554d23e2c4884a37092b1e35e1/src/sentry/lang/native/applecrashreport.py#L265

A [customer wrote in](https://www.notion.so/sentry/1c38b10e4b5d80ce9952ce3baf4bdd55) because they expected the code id instead.

Not sure if this is by design, this was the last change to the code: [PR](https://github.com/getsentry/sentry/pull/15835)

Start at src/sentry/lang/native/applecrashreport.py:265, where the debug-file ID is rendered for native raw stack trace image lists. Read PR 15835 and the linked team-ingest issue to understand the intended identifier and current unsymbolicated-stack-trace flow. Done means the rendered identifier matches the agreed behavior, with relevant coverage updated if existing tests cover this path.
