Bug Fixes

• Origin Creator name/description rejected on save as "Not a string" — the creator writes name / description as {"text": "..."} component JSON so author-entered text renders literally rather than as a translation key, but the field codec accepted only raw strings and validation failed on every save with Not a string: {"text": "..."}. The codec now accepts either form: raw strings continue to wrap as translatable components (so every shipped origin still resolves through the language file), and any vanilla component-JSON object decodes through ComponentSerialization.CODEC. Same helper is shared by the player Origin Creator, the Mob Origin Creator, and any custom origin_layer JSON.
