Polish fleet-watcher review cards

[NagyVikt]

Summary

• Replaces the flat recent-decisions list with iOS bordered review cards for fleet-watcher.
• Each PR card uses an IOS_BG_GLASS surface, IOS_HAIRLINE rounded border, status chip, quality rail, action buttons, and keyboard hint footer.

Live data sources

• Existing gh pr list feed still drives pending counts, recent review events, merged PR counts, and diff bins.
• Existing Colony review message sampling remains best-effort; deterministic fixture still renders when gh or Colony are unavailable.
