pvp tweaks

1.9.3

Added

• Fire Block Height controls — presets (vanilla/full/mid/low/flat/none) now directly control fire block height; renamed from "Entity Fire Height" to "Fire Block Height"
• Disabled widget styling — buttons and sliders render grayed out when inactive
• Flash hint on disabled crosshair settings — clicking a disabled crosshair control briefly highlights the "Custom" toggle

Changed

• Fire block height preset changes now only apply via "Save Fire" button or "Done" (no auto-reload on preset cycle)
• "Save Fire" button now only triggers chunk rebuild (no resource pack reload)
• Auto-reload tick handler removed (was causing unwanted reloads on preset change)
• Updated mod version to 1.9.3 across all supported Minecraft versions

Fixed

• GUI buttons no longer visible above the title bar when scrolling
• Crosshair Adjuster: removed the center vertical divider bar
• Crosshair Adjuster: all settings are locked when Custom is toggled OFF
