Show Top Sources for Each Nutrient (e.g., Salt, Sugar, Fat)

1. The Problem:
When my daily summary shows I'm over my limit for a specific nutrient like salt, sugar, or saturated fat, I have no easy way to see which food was the main cause. I have to manually click through all 20-30 food items I logged that day to find the source. This is very time-consuming.

2. The Solution:
Allow users to tap on any nutrient total in the daily summary (e.g., tap on the "20g Saturated Fat" line). This should open a new screen showing a ranked list of all the foods from that day, sorted from the highest to the lowest contributor for that specific nutrient.

3. The Benefit:
This feature would make Yazio much more powerful. Instead of just tracking data, it would provide actionable insights. Users could instantly understand their eating patterns and make specific, informed changes to their diet. It would help everyone to not just see what they ate, but to understand where they can improve.
