fix(models): normalize media endpoint metadata (#11397)

Validado em lote combinado (batch-0824g) contra o tip de release/v3.8.50: typecheck:core limpo, gates estáticos OK, 62/62 testes focados passando (endpoint/parser/schema/static-model + catálogo).

Canonicaliza metadados de endpoint legados (video/audio) para IDs específicos por operação, mantendo compatibilidade retroativa via `normalizeModelSupportedEndpoints` (valores antigos `audio`/`video` continuam válidos como entrada e são normalizados na escrita). Obrigado pela contribuição, primeira PR bem-vinda!
