Complete inactivity messages

♻️ Current situation & Problem

• Adds logic to complete inactivity messages whenever a user observation is changed. Before, inactivity messages were created but never completed.

⚙️ Release Notes

Add a bullet point list summary of the feature and possible migration guides if this is a breaking change so this section can be added to the release notes.
Include code snippets that provide examples of the feature implemented or links to the documentation if it appends or changes the public interface.

📚 Documentation

Please ensure that you properly document any additions in conformance to Spezi Documentation Guide.
You can use this section to describe your solution, but we encourage contributors to document your reasoning and changes using in-line documentation.

✅ Testing

• Includes tests to make sure inactive messages are correctly completed.

Thank you for the additional tests; looks great!

Would be great if we can quickly adjust the PR description to describe the PR & the fix in a few minimal bullet points.
