Fix numerous flatpak issues

https://redhat.atlassian.net/browse/PULP-1633

- Fix flatpak index cache serialization on pulpcore>=3.85
- Add domain prefix to flatpak index Name field via get_full_path
- Fix FlatpakIndexStaticCache key to include host, preventing cross-domain cache collisions
- Fix OS/architecture filters being silently dropped in recurse_through_manifest_lists
- Make test_flatpak_install domain-aware using the full_path fixture
- Fix host generation in index response when CONTENT_ORIGIN=None
- Fix CI TLS setup to use cp cert to the anchor location so flatpak/OSTree trusts the Pulp CA

Made-with: Cursor
(cherry picked from commit 1f08ceb)
