Reset pixel x/y of tactical objects when hiding behind them (#94717)

## About The Pull Request

Fixes #94180 
When you pick up an item with the "tactical" component you hide behind
it, this is primarily applied to potted plants and cardboard cutouts.
Potted plants are the kind fo item that mappers occasionally like to
adjust the position of to make them look like they're on desks or
something, however if you hid behind an offset plant then it would
maintain the offset until dropped meaning that you could appear to be in
the wrong tile.
When you pick up an item you can hide behind it will now first reset its
apparent position.

## Changelog

🆑
fix: When you pick up a plant pot and hide behind it you will now also
move it in front of you, in case it is visually far away from your
position
