feat(dashboard): collapsible Pezkuwi card, minimal by default

Card now opens in a slim single-line pill showing only Trust Score.
Tapping it expands to the full card (citizen status, world Kurdish
count, referral actions); a chevron in the expanded header collapses
it back. Expand state persists across scroll/recycling within the
session but resets to collapsed on a fresh app launch.
