-setDebugLevel NET does not enable network diagnostics

Bug Description

Network diagnostics guarded by DEBUG_LEVEL_NET are never emitted, including when NET is explicitly selected with -setDebugLevel.

This makes the existing network logging unavailable when investigating connection stalls, retransmissions, frame synchronization, or packet handling.

Reproduction Steps

1. Build and run a debug build.
2. Start the game with -setDebugLevel NET.
3. Enter a network game and generate network activity.
4. Inspect the debug log.
5. Observe that diagnostics guarded by DEBUG_LOG_LEVEL(DEBUG_LEVEL_NET, ...) are not written.

Additional Context

DEBUG_LEVEL_NET is zero, while DEBUG_LOG_LEVEL tests the level directly against DebugLevelMask.
