Broker API and candlestick update

## Prediction API update

### Broker API access

Prediction supports Broker API Keys for private REST endpoints. A Broker can call these endpoints on behalf of its users and specify the user's wallet with `X-User-Wallet-Address`. Public market data does not require authentication. See [Broker API Key and signing](https://dexbuilder.mintlify.site/en/api-reference/common/broker-authentication.md) and the [Prediction API overview](https://dexbuilder.mintlify.site/en/event-markets/api/overview.md).

### Candlestick API update

The public candlestick documentation now recommends `GET /api/v4/prediction/crypto/candlesticks`. Compared with the previously documented `GET /api/v4/prediction/tokens/{currency}/candlesticks`, the new endpoint uses the `symbol` query parameter and requires `interval`; use `start_ts/end_ts` for the time range. A successful response is an object with `symbol`, `interval`, and `history`, rather than a candlestick array. `tag_id` remains temporarily supported and must not be sent with `symbol`. The previous endpoint remains available for existing clients. See [Get Crypto Candlesticks](https://dexbuilder.mintlify.site/en/event-markets/rest/query-candlesticks.md).
