feat(map): filtros por columna en cabecera (elementos e inspecciones)

Usa la cabecera secundaria de Rappasoft (setSecondaryHeaderEnabled + secondaryHeaderFilter):
- Elementos: Elemento (texto), Capa (select), Fase (select).
- Inspecciones: Fecha (date), Elemento (texto), Resultado (select), Usuario (select);
  Plantilla sin filtro.

Tests: MapTablesTest amplía con filtro de capa funcional. Suite 75 passing.
