style: auto-format with black + isort + prettier [skip ci-format-check]

根因: plan.config 中某 key 的值可能为 bool 而非 dict，
当 .get() 或 from_dict() 被调用时崩溃。
'or {}' 只能防 None/空值，防不了 True/False。

修复策略（双层防护）:
1. 治本: 所有 from_dict 方法入口加 isinstance(data, dict) 检查
   - chroma_key_config.py / color_grade_config.py / noise_reduction_config.py
   - watermark_config.py / pip_config.py / intro_outro_config.py
   - reverse_engine.py
2. 治标: 调用方直接 .get() 处加 isinstance 防护
   - unified_render_service.py: tts/bgm/title/subtitle/export/bgm
   - render_adapter.py: bgm/export/title
   - render_audio.py: bgm/audio_tracks
   - generation.py: title/subtitle/bgm/export
   - edit_plan_generation.py: title
