Make Contract box on project page more informative

[vildead]

The box is not very informative as it displays only the project "title".

• in case of many partners involved, the title gets very long but does not contribute to overall clarity

Suggestion

1. [to discuss] enrich model of contract by name (unique in scope of a project)
2. [to discuss] enrich model of contract by contract type (DSA, CA, MTA, MDTA, Collaboration agreemnet, ...) - is there an onthology we could use?
3. display in the box more attributes - id? name, type, remarks, ...

Align with features of other systems keeping the documentation (UNI level legal?)
