Note

Switch to catalog-managed axios/express/rollbar, upgrade build/test tooling (Vite/Vitest), add SCSS preprocessor config and alias updates in Vite, and adjust test mocks/timeouts.

• Dependencies:
  • Move axios, express, and rollbar to catalog-managed versions across packages.
  • Bump dev/tooling (Vite 7, @vitejs/plugin-react-swc 4, Vitest 4 + coverage plugin, @types/node 22) with corresponding lockfile updates.
• Frontend (Vite):
  • Add SCSS preprocessor options (api: 'modern-compiler', loadPaths to scripts).
  • Clean up aliases (remove SCSS path rewrite; add models and helpers).
• Tests/Types:
  • Fix Vitest Mock typings to function signatures and explicit Set<string> generics in mocked notification providers.
  • Normalize test timeout option placement.
