[Bug] tc_frozen_katana overrides top-left weapon HUD active weapon

[wxj881027]

Description

When tc_frozen_katana is enabled, entering freeze-area state can make the top-left weapon HUD show the wrong active weapon.

This appears to be a side effect of the "katana in freeze" feature: the player model should display katana, but HUD should still reflect the real held weapon.

Version

• Latest release tested: 10.8.7
• Also reproducible on current master build (as of 2026-03-25)

Environment

• OS: Windows 11 x64
• Map mode: DDRace-like maps with freeze areas (including situations where in-freeze is true)

Steps To Reproduce

1. Enable tc_frozen_katana 1.
2. Hold a non-ninja weapon (gun/shotgun/grenade/laser).
3. Enter a freeze-area/in-freeze state.
4. Check the top-left weapon HUD (DDRace player-state weapon row).

Expected Behavior

• Player model can show katana (visual effect), but
• HUD highlight should still show the real active weapon.

Actual Behavior

• HUD active weapon becomes desynced, instead of the real held weapon.

Suspected Cause

CPlayers::OnRender mutates shared render state weapon (m_RenderCur.m_Weapon = WEAPON_NINJA) for freeze-katana rendering.
Later, HUD reads m_RenderCur.m_Weapon to determine active weapon highlight, so HUD is polluted by a model-only visual override.

Suggested Fix

Keep freeze-katana override in a temporary per-render copy used only for tee model rendering.
Do not write the katana override back into shared m_RenderCur.
