Fix omarchy-windows-vm username/password handling for dollar signs

[ajkingio]

The Issue

omarchy-windows-vm doesn't escape $ symbols in passwords so it thinks they are variables. It sets a chopped up version of the password in the Windows VM but uses the full password you passed in the docker compose file.

I noticed these messages during the omarchy-windows-vm install process, which tipped me off.

Starting Windows VM with docker-compose...
WARN[0000] The "t3rD" variable is not set. Defaulting to a blank string.
WARN[0000] The "R" variable is not set. Defaulting to a blank string.

So the manual fix was:

1. omarchy-windows-vm remove
2. omarchy-windows-vm install
3. Use a password without dollar signs.

The Fix

Fixed omarchy-windows-vm to properly handle $ in usernames/passwords by escaping dollar signs before writing docker-compose.yml, so Docker Compose doesn’t treat them as variable interpolation. Then on launch, it unescapes when reading credentials back for RDP login. This keeps the Windows account password and the stored compose config consistent.
