Frontpage update (#179)

This PR introduces an overhaul for the front page and login features while keeping the rest of the application intact.

## Major Changes

- TailwindCSS + DaisyUI Integration: Add  modern CSS framework for component-based utility styling
- Build System: Added pnpm for CSS building; can be extended for updated frontend builds in the future
- Navbar + Footer: Redesigned and includable; old version retained for unstyled elements
- Optimized Assets: Added minified and CSS-stylable logos

## New Features

- Static Pages: Added comprehensive mockups of static pages (legal, privacy policy, terms of use, contact, etc.). **Note:** These have to be fixed before a public release, as their content is largely unreviewed and incorrect. Probably best to do in a separate PR that only contains updates to these.
- Discourse API: Implement minimal features based on RestAPI for controllable results.

## Current bugs
- [x] The static pages include the default navbar and footer on the login page. This will likely not work, as users need to access it before logging in; no good workaround so far (problem with Django templating system).
- [ ] The front page predict link is currently non-functional; the redesigned page is almost ready but better done in a separate PR as it also touches Django code.
- [x] Visual bug with the news cards. Still intend to fix for this PR
