🔨 Switch Dependencies to use useOvermind

[MichaelDeBoey]

Follow-up of #3066

Things I did extra:

• Change npmDependencyRemoved's signature to accept a string instead of { name: string }, because it only has 1 argument
• Put all styles into the elements.ts file
• Make AddResource a FunctionComponent
• Move overmind subscriptions as close as possible to the components itself instead of passing it through
