Color picker field

[MlKilderkin]

What does this do/fix?

Introduce a new custom ACF field type Color Picker (color_picker_tribe) to the plugin.
This adds:

• A new field class to register a palette of named colors (slug - hex) and default value support.
• A render class to display those colors as selectable swatches in the ACF editor.
• Supporting JS / CSS in the theme to handle selection UI in the ACF editor side for meta fields.

What’s included

• wp-content/plugins/core/src/Integrations/ACF_Fields/Color_Picker/Color_Picker.php - defines the ACF field type, with fluent colors() setter and default palette extraction.
• wp-content/plugins/core/src/Integrations/ACF_Fields/Color_Picker/Color_Picker_Render.php - the rendering logic for the field in the admin (shows swatches, builds hidden input).
• wp-content/themes/core/assets/js/editor/color-picker/index.js - add wrapper for DynamicColorPicker and pass data from ACF to Gutenberg component

We're going to want a FE dev to go through this when you're ready to clean up the JS & CSS, but this is a good start to a swatch picker. Let me know when it's done and I'll take another look!

🟢 Just one note from me - looks good otherwise. It's insane to me that you were able to utilize my Dynamic Color Picker to render ACF options but here we are. Amazing work 🌮
