ci: skip postinstall in check-only jobs with setup-vp

Add run-install: false and manual vp install --filter . --ignore-scripts
for lint, i18n, and tag jobs to match original behavior and avoid running
heavy postinstall tasks (generate:lexicons, generate:sprite, nuxt prepare)
in jobs that don't need them.
