Addresses "no way to edit hands" and cleaning up misattributed ones:
- hand viewer (/hand/{id}) gets an "✎ Edit this hand" panel: position, cards,
board, your net, tag, lesson → Save (existing PATCH), plus Delete.
- "Not my hand" → POST /hand/{id}/disown → poker.disown_hand clears the flat hero
fields and rewrites structured with hero_involved=false, so a hand mislabeled as
Brian's becomes a clean observed hand (replay stops showing him as hero).
1 test. Full suite 156 green.
