Bomb and Radioactivity Behaviors (#21593)

changes:
- balance: "Dirty bomb cleanable 'greenglow' decal left behind is now
actually radioactive to make it more persistently hazardous."
- balance: "'Radioactive waste' rare Warehouse spawn submap now uses
low-radioactivity variants for some of its contents and also been given
a radioactive gear crate."
- balance: "Adds increased taste_mult values to radioactive waste,
napalm, and nitroglycerin; it should be noticeable if your drink is
spiked with any of them."
- balance: "Both uranium and radioactive waste reagents will create
radioactive pools on the floor if spilled (uranium weak, radioactive
waste medium/strong)."
- balance: "Bombs are now allowed to be planted on any mob type except
for carbons."
- balance: "Increases the numbers of assemblies (signalers, igniters,
etc.) stocked in vending machines."
- rscadd: "Adds a radioactive waste chemical canister to the Uplink (5
tc)."
- code_imp: "Adds additional variants of greenglow/radioactive decal and
radioactive_waste/hazardous obj that are more or less radioactive for
mapping and ST use."
  - code_imp: "Cleans up bomb timer setting code and admin logging."
  - qol: "Adds more examine hints to reagent dispensers."
  - qol: "Adds more examine hints to bombs."
  
The 'radioactive waste chemical canister' item cost was set to 5 tc to
match the other 'hazardous chemical' antag item, the Chlorine Tank.
