The Copy share link button on the Stats overlay only produces a URL
when the displayed replay has a `share_url` populated; otherwise it
surfaces a toast explaining the upload prerequisite. Players had no
way to know the button would work without clicking it.
Adds a "\u{2022} Shareable" suffix to the Latest-win caption when
the displayed replay carries a share_url, matching the format the
v0.19.0 handoff sketched ("Replay 3 / 8 \u{2022} Shareable") for
the future Prev/Next selector. The Prev/Next markers exist in
stats_plugin but no spawn site renders them today, so the live
fix is on the existing single-replay caption.
