feat: add reconnect action.

[iFurySt]

1. when refreshing the page or socket reconnect: try to reconnect to the already initialized agent. if it doesn't exist, auto init.
2. reset button: init agent includes related envs like docker containers.
3. change settings: init agent, same as step 2.

Hi @iFurySt , I'm just looking through the backlog and was just wondering what you'd like to do with this PR? Fix the conflicts? Close and possibly do in a different PR? Any way is fine, just checking!

I'll close this PR, it's been behind too long.
