v1.6.3

Fix — Update dialogs for Home Assistant 2026.3.1

This release fixes custom panel dialogs that no longer rendered correctly on recent Home Assistant frontend versions.

What changed

• Updated ha-dialog usage to use the current header-title API.
• Moved dialog actions into ha-dialog-footer for create group, duplicate group, and restart confirmation dialogs.

Why this matters

Home Assistant Frontend 20260304.0 changed the expected dialog structure. This update restores proper modal rendering and actions on HA 2026.3.1.

Thanks to @HotFr1dge for reporting the issue.
