One-click actions for claims, win, and kong in hand #19
Description
Dependent on #17.
When server has logic to detect claim options, we can implement one-click actions on the UI for the following:
- During claim stage, show actions if discarded tile is claimable. Possible actions are chow, pong, kong, and win.
- During discard stage, show kong and win action when possible.
With this, we don't need to select specify tiles anymore and instead present possible combinations.
