[hashlink] DebugConsole: expanding RigidBody Attributes will crash

- select an object with a Rigid Body in the ingame debug console
- scroll down to `Properties (Object)`
- click `armory.trait.physics.bullet.RigidBody [Details]`
- try to expand `Attributes` in the appearing trait view
- app will crash with `Uncaught exception: Can't cast i132 to String`

The attributes will show in Krom builds, but crash in hashlink.

Reproduce the crash in the ingame debug console by opening a RigidBody trait and expanding Attributes in a hashlink build; compare the same action in a Krom build. Trace the RigidBody Attributes view and the failing i132-to-String cast. Done means Attributes expands without crashing in hashlink while retaining the reported Krom behavior.
