fix(nand-ftl): 传输失败不再误标坏块 + format 不再被脏缓存挡死（#79）

根因（真机定案，问题 #79）：旧 dhara_nand_erase/prog() 把一切失败一律
mark_bad，而 mark_block_bad 每次**立即持久化**板级 BBT（不可撤销）——
一次传输层/等忙抖动就把好块永久记成坏块。台架 129 个好块（1016–1142
连续段）被固化，journal prepare_head() 连续 8 次撞 is_bad → TOO_BAD →
Cache flush FAIL → reformat 又被同一页挡住 → 整卷禁用、重启不恢复。

- 修复①：只有芯片明确回 E_FAIL/P_FAIL（状态位证据）才标坏；
  传输/超时失败只报 DHARA_E_BAD_BLOCK 让 dhara 重试，不标坏
- 修复②：nand_ftl_format() 尽力刷一次脏缓存，失败即丢弃并继续
  dhara_map_clear()（格式化语义本就是销毁映射；旧实现第一步返回，
  恢复动作在同一页死锁，f_mkfs 全在旧映射上必失败）
- C4 还债：新增跨调用失败类快照 nand_ftl_fault_get/clear（20 B，
  resume/读/刷/同步四点位记账）；defaultTask 探针按类分流，
  BSP_ERR_NO_SPACE 跳过重格式化（容量问题不该用 mkfs 解）
- 哨兵与诊断：init 解锁块保护（A0h）后补回读校验（与 B0h ECC 同族
  缺口，实测本板 A0h=0，非本次根因，留作哨兵）；gd5f_bbt_load()
  合并后坏块数 > 出厂扫描时打「BBT after merge」，现场可区分
  真坏与误标固化
- 测试：主机单测 149→178 全绿；新增 format 死锁（TC-NANDPORT-800..
  813b）、传输失败不标坏（207 语义翻转 + 208/505）；牙齿检查过——
  把修复回退即见红
- 真机：恢复动作 A 重建 BBT 清除已固化误标（3/3 PASSED，BBT
  version=71）；产品镜像复烧 [FS] FATFS mounted、配置出厂模板
  落盘、0 条 flush FAIL——#79 真机闭环（旧卷内容随 map clear
  作废，台架卷为可弃数据）
- 文档：存储架构说明 §10.4 口径修正 + 新增 §10.4.1/§10.4.2（页级
  失败升级链与误标持久化机理），存储维护与容量恢复 §2 补板级 BBT
  独立持久化注记 + §2.1（动作 A 此前静默失效），登记簿 C4 销项
- Keil 0 错 0 警（Code=255552，与烧录验证镜像一致）；doc-links 213
  文档通过
