test ✅: add comprehensive test suite for CSS ordering rules

Add tests for all three CSS property ordering rules:

    alphabetical-order,
    concentric-order,
    custom-order,

Tests cover all implemented vanilla-extract APIs, fontFace, globalFontFace, globalKeyframes, globalStyle, keyframes, style, and styleVariants.. Each test verifies both valid and invalid cases, along with proper auto-fixing functionality.
