[Milestones] Controller Milestones to hit before alpha

[SirBerg]

The following still needs to be done before the v0.1.0 release:

These pages need full implementation:

• Cache Settings (/app/settings) @SirBerg
• Admin Center (/app/admin) @SirBerg
• Storage (/app/storage) @SirBerg
• Performance (/app/performance) @SirBerg

These pages are partially implemented but are missing key functionality:

• User Page (/app/user) - Missing design mostly, also API Keys would be cool to add here @SirBerg
• Builders (/app/builders) - Missing: Builder Edit Page, Builder Details Page, Builder Delete Page
• Packages (/app/packages) - Missing Page selector (i.e show max 50 pkgs on one page, create multiple pages for pkgs)
• Overview (/app) - Missing Button Functionality, Missing Information @SirBerg

Other tasks to be completed before v0.1.0:

• Fix Linting Errors
• Fix api endpoint schemas (/api/v1), apparently z.custom doesn't validate the schemas correctly so all those routes need to be replaced @SirBerg
• Document Controller <-> Scheduler communication in a visual way
• Document Codepaths in Scheduler - most of the scheduler code would only be maintainable by @SirBerg atm and that's not a good thing
• Move remaining "local" types in the controller to the unified @iglu-sh/types package @SirBerg
