fix: Guild Member List & Guild Search Lists are now fully clickable + Grid fixes

[HiFlii]

This introduces two fixes: one for the Guild Menu and one for Grid in general

Copying my commit messages here:

Grid

Previously the grid would give an extra line if the placeables
was evenly divisible by itemsPerLine.

Guild Menu

Previously, the guild member list menus had the rightmost and
bottommost column/row (respectively) not be clickable. This occured
because the contents (usually a Grid) was offset and the Box containing
them was not.

This has been resolved through and admitedly hacky solution where:

1. A box is rendered as before and used to fetch the size of the contents (Grid)
2. A box is rendered whose components are blank cells to clear out step (1)
3. The final box is rendered using fillMaxSize() to ensure that the contents
   fit inside it.

This separates the size extraction and the content containing steps.

This ensures that:

• The 'itemsPerPage' or 'itemsPerLine' and 'totalLines' variables
  are of the size of the original contents instead of their enclosing Box.

• The enclosing box for the contents is of sufficient size such that all
  the elements are clickable.

Alternative solutions could include altering the spec for Scrollable and
Paginated to take in an optional Size override.

I can cherry pick the width and height fixes into the 1.21.4 branch, however the double composition of content() isn't great and I'd like to avoid that. Compose on android has layouts that can measure their own size in a better way than what we have, I'm hoping to improve the behaviour with something similar in the future. I think this specific issue can be fixed on the guild implementation end for now though, will try to have a look when I'm done cleaning those up.

Sounds good. We can revisit once you finish the guild implementation cleanup!
