feat(ui): 8 张 EAF 数字人完整接入 (m01~m08 全情绪映射)

数字人从原本 m06+m07 两张 EAF 扩展到 m01~m08 八张, 通过 ezgif 240×320 +
抽帧 N=3 + EAF Packer 配置, 8 张 EAF 总和压缩到 4.32 MB, SPIFFS 当前
4.94 MB 分区直接装下, 无需扩分区也不丢 OTA 升级能力.

main/dzbj/ai_chat_ui_eaf.c:
  - 新版/旧版 MMAP 自动检测 (header[8] == 0x14 → entry 32B; 0x10 → 28B),
    兼容在线 EAF Packer 两种导出格式 (FSIZE/FOFFSET 偏移自动适配).
  - find_cache_index_by_name 加 fallback: 找不到精确匹配时返回 cache[0],
    PoC 阶段单张 EAF 也能验证全部情绪触发.
  - emotion_map 22 情绪 → 8 张 EAF 重排:
    * 默认/积极组 12 → m01..m05 均分 (每张 2-3 种)
    * 思考/疲倦组 5 → m06
    * 负面/严肃组 3 → m07
    * 惊讶组 2 → m08
  - 数字人对齐 GFX_ALIGN_CENTER → GFX_ALIGN_BOTTOM_MID, 240×320 在
    360×360 圆屏贴底显示, 顶部 40px 透明露出背景图, 视觉跟之前
    360×360 全屏 EAF 一致 (脚部贴底, 字幕 z-index 上层覆盖底部 56px).

spiffs_image:
  - hiyori-assets.bin: 956 KB (m06+m07) → 4.53 MB (m01~m08 + index.json)
  - 删除原 GIF (hiyori_m{03,06,07}.gif), EAF 已替代不需要烧到设备.

实测数据 (Baji 2026-05-20):
  m01=814KB m02=516KB m03=563KB m04=559KB m05=606KB m06=423KB m07=379KB m08=566KB
  8 张 EAF 总和: 4.32 MB
  SPIFFS 占用: 4.58 MB / 4.64 MB 可用 = 1.3% 余量 (临界, 未来加资源需要规划)
