[client] Populate NetworkAddresses on iOS for posture checks

[MichaelUray]

Summary

The iOS GetInfo() function never populated NetworkAddresses, causing the peer_network_range_check posture check to fail for all iOS clients. The management server received empty NetworkAddresses and either blocked the peer entirely or could not evaluate network-based policies.

This adds the same networkAddresses() call that macOS, Linux, Windows, and FreeBSD already use. The function is available in the shared info.go and works on iOS via net.Interfaces().

Changes

• client/system/info_ios.go: Call networkAddresses() and populate NetworkAddresses field in the Info struct, matching the pattern used by all other platforms

Related Issues

Fixes #3968 — Posture checks peer network range failed on iPhone
Fixes #4657 — iOS Client loses all routes when Posture Checks are enabled

Testing

This change cannot be tested without macOS + Xcode. However:

• The networkAddresses() function is already compiled into the iOS binary (shared info.go)
• The same function works correctly on macOS, Linux, Windows, FreeBSD, and Android
• net.Interfaces() is available on iOS and returns interface information within the Network Extension sandbox

📝 Walkthrough

Walkthrough

The iOS GetInfo function is enhanced to discover network addresses by calling networkAddresses() and assigning results to Info.NetworkAddresses, with warning logging on failure. A comment typo referencing Android is corrected to iOS. The code adds logrus import for logging.
