**Related issue:** Resolves#48102
Changes:
- Renames `ExtractIPAMetadata` to `ExtractZIPMetadata` because the magic
bytes for zip based installers (.ipa, .msix, .zip, etc) are the same so
any zip file reaches it. If the zip does not contain an `Info.plist`
file it will now fail with `ErrInvalidType`.
- Did **NOT** make typeFromBytes return "zip" instead of "ipa" because
meta.Extension is set from that which has downstream effects.
- Added test files
The actual error message is still just "invalid file type".
# Checklist for submitter
If some of the following don't apply, delete the relevant line.
- [x] Changes file added for user-visible changes in `changes/`,
`orbit/changes/` or `ee/fleetd-chrome/changes`.
See [Changes
files](https://github.com/fleetdm/fleet/blob/main/docs/Contributing/guides/committing-changes.md#changes-files)
for more information.
- [ ] Input data is properly validated, `SELECT *` is avoided, SQL
injection is prevented (using placeholders for values in statements), JS
inline code is prevented especially for url redirects, and untrusted
data interpolated into shell scripts/commands is validated against shell
metacharacters.
- [ ] Timeouts are implemented and retries are limited to avoid infinite
loops
- [ ] If paths of existing endpoints are modified without backwards
compatibility, checked the frontend/CLI for any necessary changes
## Testing
- [x] Added/updated automated tests
- [ ] Where appropriate, [automated tests simulate multiple hosts and
test for host
isolation](https://github.com/fleetdm/fleet/blob/main/docs/Contributing/reference/patterns-backend.md#unit-testing)
(updates to one hosts's records do not affect another)
- [x] QA'd all new/changed functionality manually
- Tested adding a valid `.ipa`, a macos FMA that uses a .zip file
(alt-tab/darwin), and a windows FMA that uses a .zip file
(vnc-server/windows).
- Tested an msix file (renamed or not) cannot be uploaded or edited for
an existing msi installer
- Also tested the same things via GitOps

## Summary by CodeRabbit
* **Bug Fixes**
* Improved installer type detection so ZIP-based packages are less
likely to be misidentified.
* Fixed an error message that incorrectly referred to the wrong file
type when detection fails.
* MSIX packages are now reported more accurately when they don’t match
IPA parsing rules.
* **Refactor**
* Cleaned up installer metadata handling for ZIP-based archives.
