Feature/ordnance technician

[flex5hybrid]

About the PR

This PR ports the custom ordnance feature set and the Ordnance Technician role from Russian Marines Corps repository into Universe, adapting it to Universe's AU14 role structure and English-facing upstream standards.

It includes the new Universe-side role definitions, custom ordnance entities and assembly workflow, scanner/UI support, required recipes and reagents, and the missing custom ordnance sprite states/resources needed for the feature to function correctly in-game.

THIS PR DOES NOT CHANGE ANY MAPS

Why / Balance

This change adds a dedicated engineering/demolitions role for handling custom ordnance and makes the underlying feature usable in Universe.

Technical details

• Added Universe/AU14 job prototypes for Ordnance Technician, including base/default/RMC role variants.
• Integrated the role into departments, loadouts, vendors, antag restrictions, gamemode job slots, ID cards, and English localization.
• Ported the custom ordnance system code, shared/client/server logic, UI, and demolitions scanner support.
• Added the required ordnance-related prototypes, recipes, reagents, and autolathe entries.
• Restored missing sprite states for custom grenade, mine, mortar, and rocket ordnance casings.
• Fixed custom casing visual updates so inserting a valid detonator assembly correctly updates casing state visuals.
