Describe the bug

When configuring AIRI's speech module with Eleven Labs, the Voice Configuration section displays an "Error Loading Voices" related to reading the properties of an undefined object. This originates from providers.ts:892:36 and I've confirmed this is still the case on the development branch. Can look into this and try to fix it.
