refactor(assets): build logo/favicon URLs via withOriginBaseUrl helper

Swap the logo/favicon URL constants from the inline
`${trimTrailingSlash(import.meta.env.BASE_URL)}/public/res/...` form to the
repo's existing `withOriginBaseUrl(getOriginBaseUrl(), '/public/res/...')`
helper (already used here for the OIDC callback URL). Functionally equivalent —
same /public/res/ target, resolves in dev and the static-copied prod build — and
it keeps the logo URL absolute and consistent with clientUri for the OIDC
logoUri. No build-config change (publicDir stays false).
