Tracker: Bunker staff assignment (manufacturing / both / research) and research progress #33

Came up while reviewing #29. Builds on #6 (production, decision 012).

Bunker staff can be put on Manufacturing, Both (50/50) or Research. Research uses supplies but makes no stock; it progresses the current research project (bunker unlocks).

Scope

• A choice upgrade/setting on the Bunker: Manufacturing (default), Both, Research (decision 011's choice kind).
• Production uses the matching rate; research progress gets its own bar, resyncable (decision 010), with "project done in" and a "Project finished" event.

Data (decision 004)

Known (gta.wiki, Disruption Logistics, Profits): split between production and research, 1 unit every 20 / 17 / 14 minutes (no upgrades / equipment or staff / both). gta.wiki Bunker Research: research only "will halve the time" vs both; 51 projects.

Unknown, so it can't be built yet:

• supply use while split, and while on research only,
• research progress rate (time per project) per upgrade level and assignment.

Community numbers exist (an old GTAForums calculation, guide sites quoting ~7h per project without upgrades), but they aren't verified for the current game. Values from in-game measurement are welcome; otherwise marked estimates (decision 013) are an option.
