fix: chatbot corpus onMounted + CSS auteurs lisibilite + remove /rag placeholder

- ChatbotPensees: deplace lecture localStorage dans onMounted (fix bug hydratation SSR/CSR, corpus 'both' garanti au render initial)
- CartePensees: opacity 1, stroke-width 2px, font-weight 600 (auteurs lisibles sur fond pastel)
- pages/rag.vue: supprime la page placeholder /rag (route disparait, Nuxt retourne 404)
