### Summary
This PR adds support for `.zip` files as Windows Fleet Managed Apps
(FMAs). Zip files on Windows are treated similarly to `.exe` files and
require custom install/uninstall scripts, typically used for AppX/MSIX
packages that are distributed as zip archives.
### Changes
**Backend:**
- Added `.zip` as a supported Windows package type in
`SoftwareInstallerPlatformFromExtension`
- Updated validation to require install/uninstall scripts for zip files
(similar to `.exe` files)
- Added `addZipPackageMetadata` function to handle zip file metadata
extraction
- Updated error messages to include `.zip` in the list of supported file
types
- Enhanced `appExists` validation to detect provisioned AppX packages
(packages that are provisioned for all users but don't show up in the
programs table until a user logs in)
- Added version normalization logic to handle version string differences
(e.g., "11.2.1495.0" vs "11.2.1495")
- Updated winget ingester to recognize zip files and default to user
scope for MSIX/zip installers
**Frontend:**
- Added `.zip` to `windowsPackageTypes` in `package_type.ts`
- Updated `PackageAdvancedOptions` component to require
install/uninstall scripts for zip files
- Added validation rules for zip files in `PackageForm/helpers.tsx`
- Updated help text and tooltips to indicate script requirements for zip
packages
- Updated `software_install_scripts.ts` to include zip in default script
handling
**Maintained Apps:**
- Added Microsoft Company Portal as a maintained app example using zip
files
- Created install/uninstall PowerShell scripts that:
- Extract zip files containing AppX packages
- Provision packages for all future users (works in headless
environments)
- Install packages for the current user
- Handle both provisioned and installed package detection
**Tests:**
- Updated integration tests to include `.zip` in supported file type
error messages
- Updated unit tests for `SoftwareInstallerPlatformFromExtension` and
`SofwareInstallerSourceFromExtensionAndName`
### Use Case
This enables distribution of Windows AppX/MSIX packages that are
packaged as zip files (common for Microsoft Store apps like Company
Portal). The implementation handles both provisioned packages (for all
users) and user-installed packages, ensuring detection works in both
headless and interactive environments.
### Testing
- Updated existing tests to include zip file support
- Added Microsoft Company Portal as a maintained app example with full
install/uninstall scripts
---
**Note:** This PR follows the same pattern as `.exe` file support,
requiring custom install/uninstall scripts since zip files can contain
various content types that need custom handling.
