Multi-layered imports do not adjust filepaths correctly

[mjnagel]

Environment

Device and OS: MBP, macOS
App version: 0.27.1
Kubernetes distro being used: N/A

Steps to reproduce

1. Clone https://github.com/mjnagel/layers-of-cake
2. zarf package create
3. Observe during confirmation that only the "bottom" import has its paths adjusted correctly.

Expected result

All layers of imports should have filepaths adjusted to be relative to the import path.

Actual Result

Only the last imported component will be adjusted correctly. Note that this was reproduced with both 3 & 4 layers, and I assume this could be extended indefinitely.

Visual Proof (screenshots, videos, text, etc)

kind: ZarfPackageConfig
metadata:
  name: parent
components:
- name: file
  required: true
  files:
  - source: leaf/lfile.txt
    target: lfile.txt
  - source: cfile.txt
    target: cfile.txt
  - source: sfile.txt
    target: sfile.txt
  - source: file.txt
    target: file.txt

Severity/Priority

No clear workaround outside of symlinks, etc to make paths work.

Additional Context

This was originally seen with the bigbang extension values files, but it seems to affect all places where imported components need to adjust filepaths.
