Describe the bug

While migrating the client to the decoratorless Angular, certain issues with the CPC component while creating/updating exercises were discovered, see below.

To Reproduce

1. Click on the button to create a new exercise or update an existing exercise
2. Switch to advanced mode and Scroll down to enable continuous plagiarism
3. Verify the documented behavior above

Expected behavior

• Similarity threshold increments in 5 but minimum score in 1, this should be made uniform across both fields.
• Minimum size field only goes up to 100 (e.g. no minimum size value >=101 can be set through the UI)
• The allowed min and max days for significant similarity response should be revised and validated again.
• It is currently possible to create an exercise with invalid values (e.g. negative similarity threshold) because the server does not validate the values, an appropriate error should be returned instead
