#2185 tools/windows: enable_large_pages.ps1 helper to grant SeLockMemoryPrivilege

Descrição

### Summary

Adds 	ools/windows/enable_large_pages.ps1 to configure the 'Lock pages in memory' privilege (SeLockMemoryPrivilege) on Windows:
- Uses secedit to safely grant SeLockMemoryPrivilege to the current user (or specified account).
- Enables 2 MB large pages (MEM_LARGE_PAGES) for Strata's host expert arena (24-30 GiB), reducing TLB overhead from ~6.5M 4KB entries down to ~12.8K 2MB entries.
- Verifies administrative permissions and includes GUI fallback instructions for secpol.msc.

### What it leaves alone
- Zero runtime code touched; standalone administrative helper script only.
