/**

|
* Turn whatever a fetch/mutation threw into a user-readable string.
|

|
|
*
|
||
|
|
* openapi-fetch rethrows the parsed response body as-is (a plain object like
|
||
|
|
* `{ error, message, path, status, timestamp }` for Spring errors), so
|
||
|
|
* `String(e)` renders "[object Object]" in a toast. This helper prefers an
|
||
|
|
* Error.message, falls back to a `message` field on plain objects, then
|
||
|
|
* Spring's `error` field, and finally JSON-stringifies the rest.
