[Bug] The $ in Environment Variables becomes doubled,every time you save setting

[LSP0123]

Describe the bug

A clear and concise description of what the bug is.

The $ in Environment Variables becomes doubled,every time you save setting

Steps to reproduce the behavior:

eg: depoly ghcr.io/wg-easy/wg-easy 1.set it on webui like below： PASSWORD_HASH=$2a$12$zBIMbL5/axcluAruNwKziuRCvJCVeh0xrKB1wT7qEoOH95g2L2p4G 2.save setting. casaos will auto fix $ to $$ . it's good。 like this 3.save again，$$ was auto change to $$$$ it will be like this

Expected behavior

$ should not be double again when user save it again

I think the webui should only save that what user input .

When the user saves, the program generates app.yaml based on the user's input

update

set Value with " that is no use. casaos will auto remove " and change $$ to $$$$ when i save it it's no use
