Fix: Traefik proxy startup issues - handle null versions and filter predefined networks

Fixes two critical issues preventing Traefik proxy startup:

1. TypeError when restarting proxy: Handle null return from get_traefik_versions()
   - Add null check before dispatching CheckTraefikVersionForServerJob
   - Log warning when version data is unavailable
   - Prevents: "Argument #2 must be of type array, null given"

2. Docker network error: Filter out predefined Docker networks
   - Add isDockerPredefinedNetwork() helper to centralize network filtering
   - Apply filtering in collectDockerNetworksByServer() before operations
   - Apply filtering in generateDefaultProxyConfiguration()
   - Prevents: "operation is not permitted on predefined default network"

Also: Move $cachedVersionsFile assignment after null check in Proxy.php

Tests: Added 7 new unit tests for network filtering function
All existing tests pass with no regressions
