v0.1.7 — Narrow-width layout + duplicate error-card fix

Fixed

• Status text overlapping the title on narrow screens. Mid-scan and completion messages wrap to multiple lines on phone widths, pushing the cancel link off the card. Card now uses min-height (grows to fit) and container queries to shrink the title/icon at narrow card widths — fires on the card's own width, not the viewport, so a horizontal-stack with two narrow cards on a large desktop also benefits.
• Duplicate 'Configuration error' card appearing alongside the real card after a reload. Lovelace's own whenDefined() callback inserts the real card alongside the existing error card; my v0.1.3+ heal logic was creating a separate fresh element instead of replacing the error in-place. Now the heal logic removes the error sibling when a real card is already present.
