Add custom JavaScript event handlers to the plot

Handlers receive public data rows for rendered marks. Ordinary geom_polygon() paths and geom_sf() polygon-family, point-family, line-family, geom_sf_text(), and geom_sf_label() marks reuse the existing callback path and pass sanitized source-row payloads to custom JavaScript callbacks and Shiny-style shiny_id click updates without exposing renderer-private fields.
