Agent fallback provider changes made from web dashboard are not saved

[veikk0]

Description

If you configure an agent's fallback provider/model chain in the web dashboard, the changes aren't saved to the agent's config file.

Thus, when Openfang is stopped and started the next time, the config changes made are gone.

Expected Behavior

When you change an agent's fallbacks from the web dashboard, changes should immediately be saved to agent.toml

Steps to Reproduce

1. Run openfang start in a terminal
2. Navigate to the web dashboard --> Chat --> click on the cog to the right side of any activated agent and change the fallback to something other than the default.
3. Exit openfang (Ctrl+C in the terminal, or run openfang stop).
4. Run openfang start again.
5. Navigate to the same agent's configuration again and observe that the changes you made are gone.

Hello, Same for me, no change possible in setting windows . the "save" orange button can't be clicled.
windows 11 , OF 0.5.5 . i have to change "default model" by manually edit "config.toml"
So i can't add vault path because i don't know the variable name to put in the configfile (maybe just VAULT_PATH=?)
