Finished matches open as results

What changed

• A finished match opens as its results. Reopening the challenge link or reloading no longer starts a new battle.
• If a match ends without a player's final code, their last autosave is used. After a match, you can analyze code you kept working on without submitting it.
• Leaving one of your first casual battles costs nothing, and friend matches are labeled as friendly. Friend challenges get the Function and Full program picker.
