Expose the driver decision trace

Each disease page should show the exact rule applied, for example:
CBD 5−0 > 0; THC 4−1 > 0 → Balanced
That would have made the nine classification errors immediately visible.

No files or tests are listed, so start by locating the disease page implementation and the code path that computes the current classification result. Read the handler/controller and view/template that renders each disease page, then follow where the label is returned from the rule logic. Add the chosen rule expression to the rendered output. Done when a disease page visibly shows both the class (e.g., "Balanced") and the exact applied rule string (e.g., "CBD 5−0 > 0; THC 4−1 > 0").
