style(tramites): estandarizar barra superior con Control de Escrituras

* Header pasa de "h1 + hdr-btns chiquitos" al patrón de Escrituras:
  izq = botón "← Portal" + logo (mark + AALN Law + Control de Trámites
  Legales), der = sync-status + user-chip con avatar e iniciales +
  botón "Cerrar sesión".
* Mismo navy + 3px gold border-bottom, mismo height 58px, sticky top.
* Pulse animation en sync-dot (igual que Escrituras).
* Carga DM Serif Display + DM Sans para que la tipografía del header
  coincida con Escrituras.
* setUserChip() pobla avatar (iniciales) y nombre tras loadAll.
* Pestañas de departamentos quedan como estaban — solo el header se
  estandarizó.
