feat(HalfHour): Edited text related to half hour harvest activation
- Changed ActivationHalfHour component to host 2 different rendering.
- Changed enedis button's css
- FluidChart now queries half hour data from 3 days prior to selectedDate when the component knows traces of half hour data exist in db. When no data are retrieved, displays consent renewal button, otherwise displays related data and/or "Donnée manquante".
