Сontainer grid sizes and footprints

[ErhardSteinhauer]

About the PR

Right now, for example, a utility belt has a 2x8 inventory space, but its current footprint is 6x6, and it can't be stored in duffels or backpacks. In this PR I'm adjusting its footprint to match its actual inventory size, such as 2x8 or 4x4, and removing the restriction on placing them in larger containers like backpacks. This could similarly apply to other belt slot storage accessories or containers like toolboxes. This change should not significantly impact game balance, but it could enhance the quality of life for players in certain edge cases.

Slightly more context in this post. Here is the table of new values.

Container	Container size	Max stored size	Grid	Footprint
duffel	Huge	Huge	8x5	8x5
backpack	Huge	Large	7x4	7x4
satchel	Huge	Large	two 2x4, 4x4	8x4
messenger bag	Huge	Large	four 2x2, 4x4	8x4
toolbox	Large	Medium/Normal	7x4	7x4
belt	Large	Medium/Normal	4x4	4x4
webbing	Medium/Normal	Small	4x4	4x4
cardboard box	Medium/Normal	Small	3x3	3x3
medkit	Medium/Normal	Small	4x2	4x2
weapon case (short)	Medium/Normal	Small	4x2	4x2
weapon case (long)	Huge	Huge	4x4, 2x4	6x4
weapon case (heavy)	Ginoromous	Ginoromous	8x6	9x6

Why / Balance

I thought that something like this should be a reasonable change:
belt -> duffel/backpack/toolbox
toolbox -/-> toolbox
toolbox -> duffel/backpack
duffel/backpack -/-> duffel/backpack

How to test

Spawn various bags, try to put one in another.

• tweak: Slightly changed how wearable containers (like backpacks etc) work: now it's possible (but rather pointless) to put a belt in backpack, a backpack in duffel, a toolbox fits in a backpack.
