style: format web apps with prettier and sort imports

Apply repo-wide Prettier/lint normalization across admin-web,
desktop-client and ops-web: single quotes, no semicolons, trailing
commas, consistent line wrapping, and import ordering. Also drop an
unused brand-logo import in DesktopShell.vue.

No behavior changes — formatting only.
