♻️ Refactor webserver projects: rest exception handlers

[pcrespov]

What do these changes do?

♻️ This PR refactors error handling in the projects domain.

Highlights

• Standardizes exception handling across project REST handlers.
• Introduces unified helper functions for enveloped responses via envelope_json_response.
• Injects errors info in some of the projects rest entrypoint (this is still undecided since there are many errors in place and cannot distinguish e.g. 404 whether it is a folder or a project or a workspace or any other subresource of a project)

Related issue/s

• preparation of projects domain for API: Create Projects with Associated Data (Feb.) osparc-issues#1644

How to test
