🧩 Custom embedded app theme

Custom embedded app theme is planned for the Embedded Portal. Admins will be able to fully customize how Holistics looks inside their host app, matching brand colors, dark mode, and visual identity across the entire embedded experience.

Previously, embedded Holistics always rendered in light mode regardless of the host app's theme or brand colors. Now you can pass visual context via the embed payload and Holistics will adapt accordingly.

What's included:

• App theme: Configure colors for UI elements inside the iframe (navigation bar, dashboard header, AI panel, etc.) via embed payload
• Dashboard theme: Dynamically apply a pre-configured dashboard theme to all embedded dashboards via embed payload
