(chore) Pin all npm dependencies. Use frozen lockfiles

[DefiCake]

As part of our security strengthening efforts:

• Packages must be pinned to a version (we should have tooling to enforce this) and lockfiles are a must.
• npm should use flag —frozen-lockfile

@DefiCake regarding the 2nd point do you mean we should update the docker file to use this flag ?
