feat: el buscador de Proyectos y Actividades tambien busca en tareas

Buscador de Proyectos: ahora busca tambien en actividades y tareas de cualquier proyecto (antes
solo nombre/codigo del proyecto). Resultados en un panel flotante con la ruta completa
"Proyecto - Actividad - Tarea"; clic navega al proyecto y abre la actividad encontrada
(pestaña Tareas si el resultado era una tarea).

Buscador de Actividades (dentro de un proyecto): busca tambien en las tareas de esa actividad,
mismo panel con "Actividad - Tarea".

Nuevo GET /api/search?q=...&projectId= (global o acotado a un proyecto). Nuevos componentes/hooks
reutilizables: SearchResultsDropdown, useDebouncedValue.
