Move 'Currently watching N apps' text to Service Status card

[Copilot]

The "Currently watching N apps" text was displayed under "Required Permission Status" but logically belongs in the "Service Status" card with consistent formatting.

Changes

• Added configuredAppsCount parameter to ServiceStatusCard composable
• Added "Apps watched:" row matching existing row format (label left, value right)
• Shows "None" in error color when no apps configured, "N app(s)" in primary color otherwise
• Removed standalone text from permission status section
• Removed unused TextAlign import

<issue_description>The app home screen now has "Service Status" card with different information.

Under "Required Permission Status" there is also a text that shows "Currently watching N apps" - i think this text can be moved into "Service Status" card/box with proper formatting to match other service status info.
