Refactor network SSID/BSSID checks to be real-time async

[Copilot]

Summary

The current syncNetworkInformation pattern introduces race conditions: callers may read stale cached SSID/BSSID values before the async fetch completes. This refactors critical paths to fetch network info in real-time via async APIs.

Changes:

• ConnectivityWrapper: Added NetworkInfo struct and currentNetworkInfo: () async -> NetworkInfo that wraps NEHotspotNetwork.fetchCurrent in async/await
• ConnectionInfo: Added async overloads for activeURL(), webhookURL(), isOnInternalNetwork(), activeAPIURL() that fetch real-time network state
• ConnectionInfo+WebView: Added async versions of webviewURL() and webviewURLComponents()
• Updated callers: WebViewController, HomeNetworkInputView, ImprovDiscoverView, ConnectionSecurityLevelBlockViewModel now use async APIs for connection-critical operations
• Backward compatible: Synchronous APIs preserved for non-critical paths

// Before: race condition prone
Current.connectivity.syncNetworkInformation {
    let url = server.info.connection.activeURL()
}

// After: real-time fetch
let url = await server.info.connection.activeURL()

Any other notes

The existing synchronous APIs remain for backward compatibility. The async APIs should be preferred for any operation where correct network state is essential (connection decisions, URL resolution, etc.).

Original prompt

Task: Refactor the way app checks for SSID/BSSID/Current network information to always be realtime when accessing, for example, .activeURL().

Where to start: ConnectivityWrapper, currentWiFiSSID and currentWiFiBSSID should not be syncronous values, it will impact primarily server's ConnectionInfo, which is used in several parts of the codebase when code requires the URL to be used for an operation.

What is currently implemented: In ConnectivityWrapper we have "syncNetworkInformation" that replaces the SSID and BSSID when called, keeping them syncronous but opening opportunities for race conditions and executions without latest information.

This is a big change, make sure tests are updated and new tests are created if needed.
