Percent symbol escaped %% is not rendered propely by PR_DEBUG

[ve2opn]

Following:
PR_DEBUG("🌡️ DHT22: T=%d.%d°C, H=%d.%d%%", temp_x10 / 10, temp_x10 % 10, humi_x10 / 10, humi_x10 % 10);
is rendered by terminal:
[12-20 22:51:28 ty D][tuya_main.c:811] 🌡️ DHT22: T=19.8°C, H=42.3[0m

Example workarounds:
Use a Unicode replacement like ﹪ - Small percent sign (U+FE6A) or ％ (U+FF05 - Full-width Percent).
PR_DEBUG("🌡️ DHT22: T=%d.%d°C, H=%d.%d﹪" ...
The character specifier, as : printf("%c", '%'); does not work.

This might be caused by our most recent submission. We may need to take a look and see if there’s a better way to address this issue.

Ok, some research:

The logging system builds the output buffer in this order:
Color prefix (e.g., \033[0;32;40m for green text)
Timestamp and metadata [12-20 22:51:28 ty D][file.c:123]
My formatted message "T=%d.%d°C, H=%d.%d%%"
Color suffix (\033[0m\r\n)
When format string contains %%, it becomes a single % in the output. So the buffer ends up with:
\033[0;32;40m[12-20 22:51:28 ty D][file.c:123] T=19.8°C, H=42.3%\033[0m\r\n~~

Proposing fix for tal_log.c

function-PrintLogV.c

Update ... above did not fix ... the problem is deeper ...
