feat(cmp): restore vendor-agnostic fields + module wiring

Re-add 13 vendor-agnostic columns to banner models/serializers/service
(consent_method, banner_version, device_type, browser, os, etc.) that
were lost when another session overwrote the code. Keep vendor_consents
dict from the other session.

Add list_consents method back to BannerConsentService.

Wire CookieBanner, Loeschfristen and UseCases into Document Generator
contextBridge (CMP_NAME, analytics tools, retention months, feature flags).
