PharmQ Admin 99fd031d5a fix(windows): skip install if Tailscale already present (avoid MSI 1603) ...

A prior .exe(NSIS) install leaves Tailscale on disk but not on PATH; the MSI
then fails with error 1603 trying to install over it. Now detect the existing
binary at C:\Program Files\Tailscale\tailscale.exe and skip installation, and
treat a nonzero msiexec exit as success when the binary is already present.
