feat(photo): pie de página georreferenciado + pantalla de configuración

- FooterOverlay: franja oscura (logo izquierda, campos derecha) superpuesta
  sobre la foto antes de encolarla; tamaños proporcionales a la resolución.
- MediaStrip: capta coordenadas GPS (expo-location) al abrir el picker,
  estampa el footer con react-native-view-shot (view off-screen + onLoad),
  y añade icono ⚙ → PhotoSettings. Fallback: usa foto original si el stamp falla.
- PhotoSettingsScreen (modal): toggle general, selector de logo cuadrado,
  activar/desactivar/editar etiqueta de cada campo (proyecto, fecha, coords)
  y añadir campos personalizados con etiqueta + valor estático.
- footerConfig: persiste en meta table (clave 'photo_footer_config').
- repositories: añade getProject(id).
- navigation: ruta PhotoSettings como modal.
