Tech Debt - dependencies

[jordy2254]

Issue

With the project being on hold for a while and now coming back dependencies are a core technical debt that need addressing

Fix

• Migrate/fix dependencies of UI
  • Fix all audit issues
  • Tidy up unused dependencies
  • Replace dependencies with more modern solutions where the dependency is no longer maintained
• Upgrade backend dependencies
  • Same as UI dependencies

Effort

This is gonna be a big ticket and require a reasonable amount of manual testing to ensure that everything works as intended. it's probably going to be best to split this down into small pull requests to minimize risk.
