feat: add emotion impact annotations to gut flora indicators on mind page

- Map each emotion-related gut flora indicator to its emotional function:
  serotonin/5-HT → mood stability, dopamine → pleasure/motivation,
  GABA → relaxation/stress relief, tryptophan → sleep/mood,
  melatonin → sleep regulation, cortisol → stress level
- Display '影响情绪稳定/影响愉悦·动力' etc. below each indicator name
- Fix value display bug: backend uses indicatorValue, frontend was reading broken ind.value
- Add indicatorBarWidth() and formatIndicatorValue() helper methods
- Add CSS for new gut-indicator-impact label (pink #FF6B9D for mind page)
