Welcome space on dashboard configurable

[techsmyth]

Description

As a developer I do not want to always see an error when firing up my local environment

Acceptance criteria

• [ ] Welcome section on dashboard to be shown a) depending on a flag b) to a controllable url via settings
• [ ] Setting from server with default working for development
• [ ] Production updated to give the right values
• [ ] client updated to use the new values

Additional Context

This is also relevant from an open source approach in that we should not be hard coding production setup in the code.
