Part 4: Storage Improvements (#90783)

- Address
https://github.com/tgstation/tgstation/pull/90476#discussion_r2051701283.
Makes pill bottle code cleaner
- Datumized some more storage values(monkey guncase toolbox & crafter
toolbox) making their init slightly faster
- Moved all standard storage subtypes(bags, boxes, lockboxes etc) that
is scattered across various files & folders in the codebase into their
respective files under `code/game/objects/item/storage` folder.
This means for e.g. if you want to see all boxes in the game you can
find them in `code/game/objects/item/storage/boxes` folder & don't have
to go looking for hidden subtypes in various module files or folders
where they were hidden away.
  Makes looking for stuff & modifying these storages much saner & easier

code: organized storage subtypes under the same files & folders
