Add Poi category icons

[f1sh1918]

Motivation

For malte and netzwerk obdach we need two new category icons

Proposed Solution

Please make the new icons available via dropdown and deliver it to the frontend via api:

• mental_health
• shelter

Find new svg icons here: integreat_categories_cms.zip

api should deliver <icon_name>_<colorHex>

@f1sh1918 Are the new icons broken? When I open the svg data of a new icon nothing will be shown, while existing icons are correctly shown... 🤔 I adjusted them for use in the CMS.

api should deliver <icon_name>_<colorHex>

Currently "icon" and "color" are delivered. Should <icon_name>_<colorHex> be delivered in addition to them or now only <icon_name>_<colorHex> and no independent "icon" and "color"?
