templates/editor: corpo do editor ocupa 100% da altura disponivel

Antes: minHeight 450 em pixel fixo do Jodit limitava o corpo —
sobrava area vazia abaixo do editor.

Fix CSS-only (sem mexer no JoditEmailEditor compartilhado):

- .dte-main__editor: overflow hidden + flex column (era overflow-y
  auto). O scroll passa pra dentro do Jodit (workplace).
- .dte-editor-wrap: flex 1 + min-height 450 (preserva minimo).
- :deep(.jodit-container/workplace/wysiwyg) force flex + height
  100% + min-height 0/100% pra anular o height: 450px que o Jodit
  seta inline.

Resultado: editor sempre preenche toda area disponivel da COL 2,
expande/contrai com a janela, e o scroll do conteudo fica dentro
do proprio editor (jodit-wysiwyg).
