Bucket B: glossary entries for mslo / heli / tanya / dd

test_every_active_pack_code_has_a_glossary_entry was failing because
five active packs (spec-nuke-strike, spec-tanya-c4-strike,
combat-tanya-vs-rush, combat-heli-flank, spec-engineer-capture,
combat-naval-shore-strike) reference actor codes the ACTOR_GLOSSARY
didn't translate.

Add EN entries to ACTOR_GLOSSARY and matching ZH entries to _ACTOR_ZH:

- mslo: Missile Silo (Soviet superweapon)
- heli: Hind attack helicopter (Soviet aircraft)
- tanya: Allied hero commando (pistol vs infantry, C4 vs buildings)
- dd: Destroyer (Allied naval shore bombardment)
