修正数码管位序: DIG4=固定F, DIG5=小数位 (APP V1.00.37)

Browse Source 
- 布局: DIG1百位/DIG2十位/DIG3个位/DIG4固定F/DIG5小数位; DIG6-A华氏, DIG6-B小数点
- display_decode 重写为温度位序, 钳位 0~999.9, 删除 hex 解码
- disp 去掉 hex 模式; 删除 cli_parse_hex; disptest 序列改为温度值
- 仅 APP 改动, Boot 不动 (仍 V1.00.07)
- docs/开发日志.md: 新增 §65

原 auto 状态并回到 0.0。
- 版本：APP `V1.00.35` → `V1.00.36`（`APP_FW_VERSION_NUM` 0x00010023 →
0x00010024）。Boot 不动（仍 V1.00.07）。
## 65. 修正数码管位序：DIG4 为固定 F、DIG5 为小数位（2026-09-06，APP V1.00.37，仅 APP）
- 用户实测反馈修正数码管位序（原代码把 DIG1~5 当 5 个全功能数字位是错的）：
- **DIG1 = 百位、DIG2 = 十位、DIG3 = 个位、DIG4 = 固定标志 F、
DIG5 = 温度小数位（十分位）**；DIG6-A = 华氏标志（°F）、
DIG6-B = 小数点。
- 修改：
- `app_display.c` `display_decode()` 重写为温度位序：value 钳位 0.0~999.9，
×10 后按 `[百][十][个][F][小数]` 落位（百/十前导零消隐，DIG4 恒写
`0x0F`→seg_of_char 出 "F"），`dp_flag` 恒 1（小数位恒显示）；删除
hex 解码分支；
- `cli_core.c` `CmdDisp` 去掉 `hex` 模式（`disp <value> [f]`，0~999.9
一位小数），删除 `cli_parse_hex()`；`CmdDispTest` 自检序列改为
`0.0~9.0` → `12.3/456.7/999.9` → `36.5F/36.5C`；
- `app_display.h` 头部注释与 `display_set` 说明更新为温度位序。
- 版本：APP `V1.00.36` → `V1.00.37`（`APP_FW_VERSION_NUM` 0x00010024 →
0x00010025）。Boot 不动（仍 V1.00.07）。
