Subject: [PATCH 1/2] feat(mobile): show relative timestamp on inbox signal
 cards

Mirrors the desktop change (PostHog/code#2240): each signal card on the report detail screen now displays a short relative timestamp ("2h ago", "3d ago") in the header, sourced from the signal's own timestamp.

Reuses the existing `formatRelativeTime` util from `@/lib/format` rather than introducing a new component, since the desktop's `<RelativeTimestamp />` wrapper exists mainly to add a tooltip that has no native mobile equivalent.

Subject: [PATCH 2/2] fix(mobile): hide signal timestamp when in the future
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`formatRelativeTime` doesn't bound-check negative diffs, so a server timestamp ahead of the device clock would render as e.g. `-120m ago`. Clamp at the caller — if the timestamp is in the future, just omit it.
