fix(operator): align Pricing catalog header padding with other pages

pricing.vue nested <PageHeader> inside .stage, so the header inherited .stage's 40px horizontal + 24px top padding on top of its own — over-indenting the title and pushing it down vs every other operator page. Move PageHeader to the top level with .stage wrapping only the content below, matching index/tenants/audit/infrastructure/billing/reports.
