remove stale layer style data during deletion and load properly

[BryonLewis]

resovles #449

The style editor was using stale data from selectedLayerStyles in Pinia sotre and layer.default_style on the selected layer object

Delete now uses a new function applyStyleSelection which will set the style or a default None style if the style is undefined

resetCurrentStyle in LayerStyle.vue has been updated so that it will no longer rely blindly on currentLayerStyle.value?.id but will check availableStyles for the style and make sure it is still valid. If it is not still valid it will select the next style that is labeled is_default and finally if nothing is loaded or found it will use the none style.

in fetchAvailableLayer in layer.ts before it would only update the availableLayers it has changed to updated the selectedLayers to keep them in sync with the availableLayers before they could get out of sync.
