New feature: Improved errors and warnings on the Week Planner page

A new feature has been added to the Week Planner that makes diagnosing timetable issues much easier. Previously, spotting errors and warnings meant scanning the board for red-highlighted lesson tiles. This worked, but it could be slow and easy to miss things, especially on larger timetables.

The Week Planner now includes a dedicated errors and warnings panel that gathers all issues into one place. As soon as the solver places lessons onto the board, you can open the panel to see a list of any clashes or warnings that were generated. Each entry includes details such as the lesson, class, day, and time, along with the specific issue — for example, a teacher clash or a class being scheduled more than once in the same day.

You can scroll through multiple pages if there are many issues, making it far easier to work through them methodically. Instead of hunting around the timetable, you can simply click into the list, understand the problem, and fix it.

This small improvement makes solving timetables faster, clearer, and much less frustrating, especially when dealing with complex schedules.
