style(design): FINDING-004 — htmx vendorizat local, nu din CDN (offline-first)

Dashboard-ul incarca htmx din unpkg.com. Gateway-ul ruleaza offline (LXC/VPS
+ Cloudflare Tunnel); cand CDN-ul e blocat/inaccesibil, htmx nu se incarca si
dashboard-ul ramane static: zero polling (banner alerta blocate, coada,
mapari), butoanele de mapare nu trimit. Aceeasi decizie offline-first ca fontul
UI (FINDING-002, fara dependinta CDN).

Fix: vendorizez htmx.org@1.9.12 minificat in app/web/static/, montez StaticFiles
la /static in main.py, base.html refera /static/htmx.min.js. Verificat live:
window.htmx.version=1.9.12, fragment polls 200, zero regresie vizuala.
