feat: running timers, symptom log, search, PDF export

- dashboard: ActiveTimers widget — live h:mm:ss for any in-progress timed event (breastfeed, nap, sleep, walk…), Terminer button patches endedAt
- dashboard: reorganised quick-log groups; Santé group (Température, Traitement, Symptôme)
- events: SYMPTOM type — tag chips (Fièvre, Reflux, Colique, Éruption, Toux, Congestion, Diarrhée, Vomissement, Irritabilité, Pleurs excessifs), stored in metadata.tags
- prisma: migration adding SYMPTOM to EventType enum
- search: GET /api/search (events by notes ILIKE, journal by content ILIKE), /search page with debounced input + keyword highlight
- nav: Recherche link added to LINKS + More drawer
- growth: PDF export button — generates formatted table with all measurements, zebra rows, downloads croissance-{name}.pdf
