[tui] Startup fixes and improvements

- Fix: Fixed handling of errors or interruptions that occur early, particularly before CL args are parsed.
- Fix: Fixed deadlock on finalizing loading indication when an error or interruption occurs before it's initialized.
- Change: `.logging_multi.Process` now sets `ImageClass._supported` to `True` whether the style was forced or not.
  - Eliminates support checks in child processes.
