crawl4ai version

0.6.2

Expected Behavior

The instance variable proxy_config of the BrowserConfig class supports the Dict type. The example is as follows

However, when proxy_config passes in Dict type data, AttributeError: 'dict' object has no attribute 'server' will be raised when ProxySettings is initialized.

When proxy_config passes in Dict type data, the ProxySettings class initialization should not throw an exception

Current Behavior

When proxy_config passes in Dict type data, AttributeError: 'dict' object has no attribute 'server' will be raised when ProxySettings is initialized.

Is this reproducible?

Yes

Inputs Causing the Bug

The proxy_config instance variable of the BrowserConfig class passes in Dict data for initialization. Since no data processing is performed on it, self.proxy_config is of Dict type.

see https://github.com/unclecode/crawl4ai/blob/main/crawl4ai/async_configs.py#L442

The self.config used to initialize the ProxySettings class is an instance of the BrowserConfig class. As can be seen above, self.config.proxy_config is of Dict type, so when executing self.config.proxy_config.server, AttributeError: 'dict' object has no attribute 'server' is thrown.

see https://github.com/unclecode/crawl4ai/blob/main/crawl4ai/browser_manager.py#L641

Steps to Reproduce

Run the following code to reproduce the exception
