build(loader): request UAC elevation via requireAdministrator manifest

Browse Source 
OpenZenLoader.exe now ships with a requireAdministrator manifest
instead of asInvoker. The Windows loader prompts for UAC consent
once at launch, which:

- guarantees OpenProcess / VirtualAllocEx / CreateRemoteThread
  succeed against javaw.exe when the Minecraft launcher (HMCL,
  MultiMC) was itself started elevated,
- avoids the silent injection failure observed on locked-down
  standard user accounts.

The EXE also picks up the UAC shield overlay on its file icon.
