Idle Cinematics 1.0.3

Camera rendering and perspective reliability update.

• Removed fragile terrain and frustum mixins that caused production modpack incompatibilities.
• Fixed IDLE leaving players in third-person view after alt-tabbing or pausing during a cinematic.
• The cinematic camera now renders the local player and hides first-person hands without changing the player's perspective setting.
• Ensured cinematic renderer state is cleaned up when pausing, disconnecting, or opening another screen.
• Preset selection details are now logged only when the preset debug option is enabled.
