Chekov's Canister! Adds missing resupply canisters, makes them constructable & spawn in maint,. (#93028)

## About The Pull Request

This is was created because I found several rare and exciting canisters
in game and then finding out there is no way to actually construct the
vendor they belong to!...

### This PR:

* Makes all noteable vendors constructable, if you have the canister. 
* Adds canisters to syndismokes, syndiechem, liberation station,
magivend, shambler's juice and bombuddy
* Replaces the old tptally random canisters spawner, with a variety of
spawners weighted for power and split according to different themes.
* Adds the new main canister spawner to maint. 

### Spawner weights

The random canister spawner from maintenance has a:

* **93,5%** chance to spawn a common station vendor refill(with weights
for wardrobes being somewhat reduced.)
* **6%** chance to spawn a rare and special vendor refill.
* **0.5%** chance to spawn a oddity level., super powerful vendor
refill.

## Why It's Good For The Game

One must never place a filled canister in maint if it isn't going to be
constructed It's wrong to make promises you don't mean to keep.

## Changelog
