feat: add AVD device filtering with optional name‑based override

[Handover2AI-byExistence]

Summary

This PR introduces flexible Azure Virtual Desktop (AVD) device filtering to the Export-IntuneManagedDevices script.

What’s New

• Added -AVDDevices switch to enable filtering for both AVD single-session and multi-session hosts.
• Added -AVDUniqueIdentifier parameter to support tenant-specific naming conventions.
• Default behavior filters AVD devices using model = "Virtual Machine".
• When -AVDUniqueIdentifier is provided, the script filters devices by matching the identifier within deviceName.

Why This Matters

Intune does not consistently expose operatingSystemEdition for AVD hosts, making OS-based filtering unreliable.
This update provides a predictable and tenant-agnostic way to target AVD devices while still allowing precise overrides when naming conventions are available.

Backward Compatibility

• No changes to default behavior unless -AVDDevices is explicitly used.
• Existing exports and authentication flows remain unchanged.

Testing

• Verified filtering using both default model-based logic and custom name identifiers.
• Confirmed correct device counts and expected output in JSON and CSV exports.
