fix Tgui error year display (#95086)

## About The Pull Request
If we look closely at the world init, we clearly see that GLOBS are not
populated by the time Subsystem PreInit is called. This led to the
current year never being properly displayed in the TGUI bluescreen
```
 * WORLD INITIALIZATION
 * THIS IS THE INIT ORDER:
 *
 * BYOND =>
 * - (secret init native) =>
 *   - world.Genesis() =>
 *     - world.init_byond_tracy()
 *     - (Start native profiling)
 *     - world.init_debugger()
 *     - Master =>
 *       - config *unloaded
 *       - (all subsystems) PreInit()
 *       - GLOB =>
 *         - make_datum_reference_lists()
 *   - (/static variable inits, reverse declaration order)
 * - (all pre-mapped atoms) /atom/New()
 * - world.New() =>
 *   - config.Load()
 *   - world.InitTgs() =>
 *     - TgsNew() *may sleep
 *     - GLOB.rev_data.load_tgs_info()
 *   - world.ConfigLoaded() =>
 *     - SSdbcore.InitializeRound()
 *     - world.SetupLogs()
 *     - load_admins()
 *     - ...
 *   - Master.Initialize() =>
 *     - (all subsystems) Initialize()
 *     - Master.StartProcessing() =>
 *       - Master.Loop() =>
 *         - Failsafe
 *   - world.RunUnattendedFunctions()
 ```
