melissa/paciente-docs: fix drawer mobile (teleport body + style global)

Bug: drawer abria mas travava — sidebar interna nao aparecia.
Duas causas combinadas:

1. position:fixed preso em stacking context: o MelissaPaciente
   tem transform/filter num ancestral, fazendo o fixed virar
   relativo ao pai em vez da viewport.
2. Styles scoped: ate corrigir o stacking context, ao teleportar
   pro body os data-v scoped attrs sumiriam e o CSS nao aplicaria.

Fix:
- <Teleport to="body"> wrap nos elementos drawer + backdrop. Saem
  da arvore do componente e ficam no body raiz.
- Styles do drawer movidos pra um <style> NAO-scoped no fim do
  arquivo. Classes globais .mpd-mobile-drawer* garantem que
  aplique nos elementos teleportados (que perdem data-v).
- Fallbacks adicionados nas vars CSS (--m-bg-medium, --m-border,
  --m-text) caso o body nao tenha o tema melissa carregado.
