feat(activities): ownership + status badges on cards & detail

ActivityCard now renders a "Yours" badge (top-right corner of the
image) when activity.isMine, and a "Pending review" / "Rejected"
badge (bottom-left) when activity.lnbitsStatus is non-approved. The
creator can spot their own posts at a glance on the main feed —
particularly important for pending drafts that don't exist on
Nostr yet.

ActivityDetailPage echoes both badges next to the category row so
users landing on the detail link of their own draft have the same
signal.
