fix(canvas): Apply pasted Pipe and Kamelet templates

[ThomasHartDev]

When you copy a full Pipe or Kamelet and confirm replace, Kaoto currently resets to a blank template. Those resources inherit a no-op addNewEntity, so the pasted steps never land.

This implements addNewEntity for Pipe and Kamelet so the copied definition is applied, including beans, error handler, and metadata. Paste now hands those resources the raw clipboard definition. KameletBinding inherits the Pipe path.

Fixes #3446

I ran yarn workspace @kaoto/kaoto test, lint:fix, lint:style:fix, and build.

Summary by CodeRabbit

• Bug Fixes
  • Improved paste and replacement behavior for routes, pipes, and kamelets.
  • Pasted single-entity definitions are now applied in the expected format.
  • Replaced resources now correctly refresh metadata, intermediate steps, beans, and error handlers.
  • Removed stale configuration when replacement data does not include beans or error-handler settings.
• Tests
  • Added coverage for pasted entity replacement and associated configuration updates.

📝 Walkthrough

Walkthrough

Paste handling now passes complete definitions for single-entity resources. Kamelet and pipe resources replace their current data and rebuild visual and supporting entities. Tests cover intermediate steps, beans, error handlers, and payload shapes.

Changes

Complete paste replacement

Layer / File(s)	Summary
Kamelet replacement and metadata synchronization packages/ui/src/models/camel/camel-k-resource.ts, packages/ui/src/models/camel/kamelet-resource.ts, packages/ui/src/models/camel/kamelet-resource.test.ts, packages/ui/src/models/camel/kamelet-binding-resource.ts	Kamelet replacement now applies the pasted template, rebuilds flow and beans entities, synchronizes metadata, and clears absent beans. The unused binding stub was removed.
Pipe replacement and error-handler rebuilding packages/ui/src/models/camel/pipe-resource.ts, packages/ui/src/models/camel/pipe-resource.test.ts	Pipe replacement now applies the pasted template, preserves intermediate steps, rebuilds error handlers, clears absent handlers, and synchronizes metadata.
Paste template selection and validation packages/ui/src/hooks/usePasteEntity.ts, packages/ui/src/hooks/usePasteEntity.test.tsx	Single-entity resources receive raw definitions. Multi-entity resources continue to receive name-keyed definitions. Tests verify both payload shapes.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to c4af2

Pasting full Pipe and Kamelet definitions now applies their steps and supporting metadata instead of resetting to a blank template. The change is mergeable with owner awareness that malformed pasted content could still leave the editor in a partially replaced state if reconstruction fails.

Poem

A rabbit pasted routes in a row
Complete little flows began to grow
Pipes kept each step
Kamelets found beans
Old handlers cleared cleanly below
