[Web] Restore enabled on a full config replace

[j-piasecki]

Description

The web GestureHandler kept the previous enabled value when a full config replace did not carry the key. It now falls back to true, matching Android and iOS.

Test plan

Added a test in GestureHandler.test.ts.

📝 Summary

Summary by CodeRabbit

• Bug Fixes

  • Gesture handlers now become enabled by default when configuration does not specify an enabled value.
  • Updating a disabled handler with otherwise empty configuration correctly restores its enabled state.

• Tests

  • Added coverage to verify the default enabled behavior.

Walkthrough

The web gesture handler now defaults omitted enabled values to true. A regression test verifies that applying an empty configuration re-enables a disabled handler.
