feat(maria-dashboard): reset pentru firele de discutie active

Nu exista nicio cale sa resetezi manual un fir blocat pe o discutie
veche (nici comanda de chat, nici buton) — un test in grupul "Maria
Test" a ramas ancorat pe un subiect vechi fara sa poata fi curatat
fara interventie directa pe server. Sectiune noua in dashboard, intre
"Trimise la suport" si "Clienti cunoscuti": listeaza firele active
din ~/.maria-bridge/conversations/ si le sterge la cerere (rutele
GET/POST /api/maria/fire), cu aceeasi sanitizare de nume de fisier ca
rag/fir.py (oglinda, nu import — coliziune de modul intre proiecte).

11/11 teste (6 noi + cele de clienti), fara regresii.
