fix(codex): write config to ~/.codex/ not %APPDATA%\codex\

Codex CLI reads config from %USERPROFILE%\.codex\config.toml
but PowerShell fallback was writing to %APPDATA%\codex\config.toml.
Old broken config remained in ~/.codex/ causing TOML parse errors.

- Fix config path: $env:APPDATA\codex → $env:USERPROFILE\.codex
- Add cleanup step to remove broken config before patching
- Remove old config before writing new one
