Harbor Tavern Pool Table bugs and UX papercuts

I've been testing out the pool table minigame and there are some (minor in the scheme of things) issues that affect playability.

- You can't drag beyond the table boundaries for shot strength (this one might be intentional to make things harder?)
- Unclear what the reward criteria are (is it one silver coin each after 5/10/50 wins count?)
- Angle/strength indicator keeps glitching out
- If you accidentally click outside the modal it dismisses the game (there are many modals in MD where this should be the expected behavior and isn't. And here it's the opposite)
- I think it lets you resume a game, but it either told me I was the wrong set (stripes vs. solids) or it added back different balls, or something else that made it confusing so I was aiming at the wrong thing.
