[Screen Toolkit] The position of Pin overlay is out of screen

[xiaoyaoshengy]

@ycf-anon Thank you for this nice plugin!

When using the Pin Screenshots feature to pin many screenshots, I noticed that the initial positions of some pinned screenshots gradually shift toward the bottom-right corner, eventually causing the pinned screenshots to appear outside the screen. From the source code, I found that _nextPinId keeps increasing, which causes offset to increase as well, ultimately leading to the above issue.

Line 32 in 5d73242

var offset = _nextPinId * 28

A possible solution: add a check when calculating the initial position to ensure it stays within the screen.
