Duiffel Spotfix (#76442)

## About The Pull Request

Gives duffelbags their proper slot count
They inherited this from backpacks, but I sorta just forgot about that

[Creates "levels" of locked objects, uses that to make locked duffels
work](https://github.com/tgstation/tgstation/pull/76442/commits/c613c00f62fa3ff03bb33737d24da9acbf2050e3)

[c613c00](https://github.com/tgstation/tgstation/pull/76442/commits/c613c00f62fa3ff03bb33737d24da9acbf2050e3)

Turns locked into something that holds defines, this makes life a lot
easier.
Requires a lot of boilerplate because of how many uses of these procs
there are and all the passthrough and shit.

Adds a few outfit subtypes to avoid this class of failure in future.

Renames the args in a few but not all touched procs, one thing at a time

Closes #76407
Closes #76430 Had the lock check in the wrong place
Closes #76441 GOD I HATE TK SO MUCH

Wrote half the pr without glasses so if it's weird gimme some grace
yeah?
