Server.vue rendered the backend-generated WireGuard peer QR with raw
v-html while the analogous TOTP QR was DOMPurify-sanitized — both now
use the same svg-profile sanitizer. Mesh.vue's 5s poll interval gets
the same start-guard as the arch poll (no leak on double-mount) and is
nulled on unmount. curatedApps.ts catalog fetches no longer fail
silently: each failed source logs a console.warn, including the final
all-sources-failed fallback to the hardcoded list.
