[FEATURE] Interaction avec zone

Sur la carte, on veut pouvoir interagir avec les zones via un clic (contexte à définir).
On peut donc déjà créer ou compléter une route qui sert les données :

/zones/{zone_id}/details par exemple => Return the list of vessels that either visited the zone or fished in the zone with the activity duration
(parameters : start_at, end_at, type = VISIT | FISHING)
{
   id: Union[int, None] = None
   category: str
   sub_category: Union[str, None] = None
   name: str
   json_data: Union[dict, None] = None
   reglementation_start_at: datetime (date de début de mise en place de la zone)
   reglementation_end_at: datetime (date de  fin de mise en place de la zone)
   activities : 
        [
            {
              vessel : {
                  id: Union[int, None] = None
                  mmsi: Union[int, None]
                  ship_name: str
                  country_iso3: str
                  type: str
                  imo: Union[int, None]
                  ircs: Union[str, None]
                  length: Union[float, None] = None
                  
              }
             duration: Optional[timedelta]
            }
        ]
}

Start by locating the existing zone routes and the entry point for vessel activity data, then compare their models with the proposed /zones/{zone_id}/details response. Clarify the click interaction, VISIT/FISHING behavior, date filters, and duration definition before implementing; done means the agreed endpoint returns the specified zone, vessel, and activity fields.
