Adapt cookie banner UI and texts per regulation

The server now resolves regulation-specific translations
(opt-out notice for CCPA, simple notice when no regulation
applies) and remaps text keys before returning the config.
The client hides buttons whose text is empty, so the banner
layout adapts without client-side consent-mode logic.
