[backend/frontend] feat(netexec): add NetExec injector integration with 12 new finding types (#4989)

[Seb-MIGUEL]

Summary

• Add 12 new ContractOutputType entries and their corresponding OutputProcessor handlers for NetExec findings (credentials, kerberoastable accounts, shares, vulnerabilities, etc.)
• Add unit tests for all 12 OutputProcessor handlers
• Register NetExec in the catalog (catalog-integrators.json) and health check registry (ExternalServiceDependency)
• Add frontend support: new finding icons and contract output element cards

Closes #4989
Related to #OpenAEV-Platform/injectors#188 and OpenAEV-Platform/client-python#192

Test plan

• CI passes (build + existing tests)
• 12 new OutputProcessor unit tests pass
• NetExec appears in the catalog/marketplace
• New finding types render correctly in the frontend

Ah yes, into another PR. Sorry. Let's track #4975 instead.

#4975 is merged, so I’m picking this up again. The code looks good so far, but I’ll follow up with tests.

Please remember to reparent the findings processors to the FindingsCapableProcessor base class.

Additionally, I will be vigilant with the auto testing, specifically please cover from the process() method to ensure a real coverage 🙏

Small nitpicks. I'm approving ahead of fixing so that you can go forward without requiring more involvement from me, but please do consider the comments!

Thanks for the tests
