v0.8.6 — a Competitive seat gets its save when the game is over

Jesse's ruling on TODO #117: accept the leak in Co-op; otherwise, save only at the end of
the game. `/api/save` answers 403 SAVE_AFTER_FINISH to a Competitive seat while the game
runs, and serves a Co-op or one-seat game at any time. The Save replay button says why and
stays disabled until the end. Pinned in the HTTP suite; documented in rules.md §6.4.

Also corrects the 0.8.3 changelog entry: 0.8.2's notes did name the Second Section card
going into the deck; what was missing was the save check after it.
