feat: 全應用播放按鈕統一為藍底漸層設計 + 架構簡化

組件統一:
• 創建 BluePlayButton 統一組件 - 支援 sm/md/lg 三種尺寸
• 替換 10 個組件中的播放按鈕為統一的藍底漸層設計
• 移除 AudioPlayer 中間層抽象，直接使用 BluePlayButton

清理優化:
• 刪除未使用的 TTSButton 和 AudioPlayer 組件
• 簡化組件架構，每個組件內建 TTS 播放邏輯
• 統一 speechSynthesis API 使用方式

視覺統一:
• 藍底漸層 + 綠色播放中狀態 + 波紋動畫
• 響應式尺寸適配不同使用場景
• 完整的播放/暫停/禁用狀態設計
