🔖 Feature description

Do not allow "Apply" if there are dates inconsistent with status:

• if status is todo, done and cancelled date should be empty
• if status is done, cancelled date should be empty
• if status is cancelled, done date should be empty

✔️ Solution

Check dates against status in DateEditor for cancelled and done dates.

❓ Alternatives

No response

📝 Additional Context

• Developed from Edit task modal: valid done or cancelled date input should set status to done or cancelled respectively #3129

If/when this is done, the #2986 and #3136 may be irrelevant
