fix(media): aplica estado 'não disponível' a imagem, vídeo, documento e sticker

Estende o tratamento de erro 400/404 do redownload para todos os tipos
de mídia. Quando mediaUnavailable=true (payload ausente no backend),
cada tipo exibe sua mensagem específica e desabilita o clique:
- Imagem: 'Imagem não disponível'
- Vídeo: 'Vídeo não disponível'
- Documento: 'Arquivo não disponível' + cursor-default
- Sticker: 'Figurinha não disponível'
DocumentBubble recebe nova prop mediaUnavailable para controle interno.
