🔨 Switch Server to use useOvermind

[MichaelDeBoey]

Follow-up of #2535 & #2818

Things I did extra:

• Change deleteEnvironmentVariable's signature to accept a string instead of { name: string }, because it only has 1 argument
• Change onBrowserFromPortOpened's signature to accept a ServerPort instead of { port: ServerPort }, because it only has 1 argument
• Extract ControlContainer, OpenPorts, RunScripts, SecretKeys & Status out of Server
• Put all styles into the elements.ts file
• Move overmind subscriptions as close as possible to the components itself instead of passing it through
• Make EnvEntry, EnvModal, RunScripts (was called Tasks) & Status a FunctionComponent
• Use FunctionComponent instead of React.FC, since it's the same, but FunctionComponent is a bit clearer I think

Hey!

I am so sorry for the work but right now we can't accept changes to the sidebar since we will be releasing a new version of the sidebar next week and all this code will be deleted

I know you made some changes also to the actions but the work it would be to make it work in the new one two days before deployment doesn't make sense right now

I'm sorry we didn't make this public :/
