Feat: Add option to ignore non-zero application exit codes

Introduces a new feature allowing application installations to succeed regardless of their exit code. This is useful for installers that may return non-standard exit codes which should be treated as successful.

Changes include:
- A new checkbox in the UI to enable this option for an application.
- Updates to the application installation script to handle the new setting.
- Modifications to save and load this setting in the application list.
