Fix foreground notification being mandatory and more. Details:
- Adds start_service_not_as_foreground() to avoid always displaying an associated notification without this being configurable at runtime. It only is configurable right now if setting the foreground property via --service, which cannot be done when using the simpler service/main.py entrypoint - Fixes service_only service code template not rendering .foreground correctly since it added an outdated, useless function name override - Fixes notification channel name which is visible to end user hardcoding "python" in its name which is not ideal for end user naming (since the average user might not even know what python is) - Fixes override of doStartForeground() leading to quite some error-prone code duplication
