batch: Fix batch file (Sygil-Dev#920, Sygil-Dev#605)

- Allow reading environment.yaml file in either LF or CRLF
- Only update environment if environment.yaml changes
- Remove custom_conda_path to discourage changing source file
- Fix unable to launch webui due to frontend module missing (Sygil-Dev#605)
