[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

Fixed in the inkly distribution of CasaOS, v0.4.41.

The escaping was not idempotent. The settings page is served YAML that already has $ written $$ (that is how a literal dollar is spelled in a compose file), and the save handler parsed it with interpolation switched off, so the generator escaped it a second time — and a third on the next save. The install path always parsed with interpolation on, which is why a freshly installed app was fine and only re-saving broke it. The handler now does the same, so a round trip through the settings form, or through the raw compose editor, leaves the value alone.
