Replaces the custom made auth-backend (auth-gateway) with its token logic and complexity
with established open-source FIPS 140-2 compliant authentication solution.
Current code uses newly deployed keycloak within kind deployment script,
but some todos are left and should be further developed.
Does not use auth-gateway anymore for authentication,
only as a proxy to extract authorization and user information from token for downstream apis.

solves #28

Added a main webpage to web/app with a navbar to control login/logout and add/select/remove a database to be queried. Restructured the main dashboard to use tailwindcss. Ported the websockets and broker implementation to V1 and tied all components (schema, querybuilder, and visualizer) together.

Solves #21

Ported querybuilder pills, edges and interactions from V1 and added stories for each pill. Ported drag-and-drop functionality between schema panel and querybuilder (plus story). Also ported Navbar for the dashboard.

Solves #20, #19, #25

This restructures the worspace int a turborepo with a (for now) single shared library with all shared components within. It includes vite build, vitest, and storybooks. Huski and CI are configured to lint and test the code.

Solves #19 and #20
