[Run] Improve error MessageBox

[davidegiacometti]

Summary of the Pull Request

This is not a fix to the error, but an improvement to MessageBox error title since it's not clear to the user that the it's related to PT Run.
This was partially addressed by #25095, but not for all the errors.

Detailed Description of the Pull Request / Additional comments

• Assessed the MessageBox.Show(...) errors that could be triggered on startup, detecting which need to explicit call out "PT Run"
• Aligned loading/initialization error messages.
• Don't think that IPublicAPI.ShowMsg(...) dialogs need "PT Run" in title since they are usually showed as a response to a user interaction (example click on a result or action).

Validation Steps Performed

@davidegiacometti
There are two plugin init error msg boxes. Did you check if the title is used in both of them?

[davidegiacometti]

I'll check. Thanks for pointing out this.

I have verified and one plugin error dialog was addressed in #25095.
This PR aim to fix the remaining and another related to the hotkey.

Thoughts regarding the init error message:

1. We should update the content of the init error message to be aligned with the title. (Loading vs initializing.)
2. Can we improve the text to be in line with the loading error text? (First list the affected plugins and in the next paragraph give some advice what to do.) That makes it easier to understand what plugins are affected, I think.
3. I think we should use the same advice like in the loading error message.
