fix(kamelet-resource): access route.from instead of from in test

[lhein]

Fixes #3446

Fixes the TypeScript build error reported in #3838.

The test in kamelet-resource.test.ts accessed .from directly on the result of toJSON(), but KameletVisualEntity.toJSON() returns { route: RouteDefinition } — so from is nested under route.

Fix:

- const from = resource.getVisualEntities()[0].toJSON().from;
+ const from = resource.getVisualEntities()[0].toJSON().route.from;

This is a companion fix to #3838 by @ThomasHartDev.

Summary by CodeRabbit

• Bug Fixes
  • Improved pasting of Kamelet and Pipe templates so their definitions are applied correctly.
  • Pasted templates now rebuild visual flows and related configuration, including route-template beans and error handlers.
  • Removed stale visual elements when replacement content no longer includes them.
  • Resource metadata is refreshed after pasted content is applied.
  • Added coverage to verify template replacement and paste behavior across supported resource types.

📝 Walkthrough

Walkthrough

Paste handling now passes raw definitions for single-entity resources. Kamelet and Pipe resources rebuild visual entities and metadata from pasted templates. Tests cover replacement content and removed nested entities.

Paste entity replacement

Layer / File(s)	Summary
Template shape selection packages/ui/src/hooks/usePasteEntity.ts, packages/ui/src/hooks/usePasteEntity.test.tsx	usePasteEntity passes wrapped definitions for multi-entity resources and raw definitions for Kamelet and Pipe resources. Tests verify both argument shapes.
Resource visual entity rebuilding packages/ui/src/models/camel/camel-k-resource.ts, packages/ui/src/models/camel/kamelet-resource.ts, packages/ui/src/models/camel/pipe-resource.ts, packages/ui/src/models/camel/kamelet-binding-resource.ts, packages/ui/src/models/camel/kamelet-resource.test.ts, packages/ui/src/models/camel/pipe-resource.test.ts	Kamelet and Pipe resources replace their templates, rebuild flow-related entities, synchronize metadata, and clear absent beans or error handlers. The unused Kamelet binding method is removed. Tests cover these replacement paths.

I have noticed a small bug in the implementation: when copied a pipe or a kamelet and pasted again, the product is correct but it appears hidden. Check this video (it appears only the pipe case but with kamelet is the same):
