[Bug] ?tab=registered URL param from ParakhAI redirect silently ignored on AI models page

Summary

When a user clicks "Add A New Model" on ParakhAI, they are redirected to:

https://dev.civicdataspace.in/dashboard/organization/{org}/aimodels?tab=registered

The CivicDataSpace AI models page only has Draft and Published tabs. The ?tab=registered param does not match any tab and is silently discarded — the page defaults to the Draft tab.

Impact

• Minor UX inconsistency: the intended landing tab is unknown
• If registered was meant to select the "Published" tab (models registered for evaluation), the redirect is landing on the wrong tab

Fix Recommendation

Either:

• (a) Update the ParakhAI redirect URL to use ?tab=draft or ?tab=published matching the actual tab values
• (b) If a "Registered" tab is planned, implement it; otherwise update the ParakhAI redirect

Note: The ParakhAI side of this is in the ParakhAI-frontend repo. This issue covers the CivicDataSpace side (unrecognised param not defaulting gracefully or logging a warning).

Environment
