[FEATURE] Wrap EmployeeManager and expose employee appearance APIs

[ifBars]

Feature Request

What would you like to see?

Add an S1API wrapper for the base-game ScheduleOne.Employees.EmployeeManager so modders can access employee appearance data through a supported API surface.

The immediate goal is to expose employee appearance APIs such as:

• GetAppearance(bool male, int index)
• GetRandomAppearance(bool male, out int index, out AvatarSettings settings)

Why would this help?

Right now, modders who want employee appearance presets have to reach into base-game types directly.

A wrapper around EmployeeManager would make it easier to retrieve the preset avatar settings and mugshot/icon data used by employees without reflection or direct raw game-manager access.

Extra Context (Optional)

Useful outcome:

• provide access to the live base-game EmployeeManager instance
• expose GetAppearance(bool male, int index)
• expose GetRandomAppearance(bool male, out int index, out AvatarSettings settings) or an S1API-friendly equivalent
• expose returned appearance data in a modder-friendly way, including avatar settings and mugshot sprite
• document how modders should use it to inspect employee appearance presets
