Update Dashboard cards

Use HTML b/i tags for Enroll and Learn more link styling

HA markdown card strips CSS font-weight/font-style, so use
<b> and <i> tags instead for bold and italic rendering.

Update VPP Matches card appearance

• Align aesthetics with CP brand
• Update language for clarity

Fix loading state

Add loading state to VPP match sensor

Return None (unknown) until first match computation finishes,
so dashboard cards can show a loading indicator instead of
immediately displaying "No matching programs found."

Loading state, key entry, and region matching

• Loading state for dashboard cards
• Mask API key entry
• Fix VPP region matching: derive user state from HA location to prevent cross-border false matches
