feat(client): elevate auth pages with a two-column brand layout

- BaseAuthPage now renders a left form column and a right brand panel with eyebrow / tagline / description copy and a chess-board pattern over the brand green gradient
- Move the language selector and theme toggle to the page's top-right inside the form column so they read clearly in light and dark
- Every auth page (login, register, recovery, set new password) inherits the new layout
- Add brandPanel translations across all 16 locales; phrase the tagline as "your servers" instead of "stack" so it translates cleanly
