[Bug] [Runtime] [Player Actions]

About the PR

Fixes #25572

This PR both corrects a division by zero runtime error and resolves the linked issue by bounding dance speed to reasonable BPMs.

Why's this needed?

After reproducing issue #25572, I discovered that the bug only occurs when time_per_count equals zero. I don't know exactly why it happens, but it's accompanied with a division by zero runtime error. Realistically speaking, dancing at a time per count equal to zero shouldn't even be possible-- that would just be standing. Dancing at a negative BPM also doesn't make sense, so this PR just limits player adjustments on time_per_count such that they're always greater than zero.

Dancing with a very slow time per count can allow players to maintain a prolonged and subtle sprite shift that is both potentially advantageous in combat and antithetical to the concept of dancing. (Not to mention that it's difficult to return from since you have to spam the "faster" button to get it back to a reasonable speed.) Aside from that, it also leads BPM towards zero (though it might not actually ever reach it due to the nature of whatever decaying function may be said to represent its slowing decrease).

Testing

On a debug build of the codebase I spawned a pair of dancing dress shoes and verified that the bounds worked as expected when speed was adjusted.
