Terminal utf8 and reconnect (#14895)
* fix: handle incomplete UTF-8 sequences in terminal output, rework on https://github.com/rustdesk/rustdesk/pull/14736
* Fix terminal auto-reconnect freeze: reconnect resumes terminal output, while multi-tab reconnect avoids restoring duplicate tabs for terminals that are already open.
* fix(terminal): subtract with overflow
```
