Fix event handler signatures for keep-alive connection events

[Copilot]

ConnectionKeepAlive._emit_event() passes a data argument to event handlers, but the client handlers didn't accept it, causing TypeError: _on_keep_alive_connected() takes 1 positional argument but 2 were given.

Changes

• _on_keep_alive_connected: Add data: Dict[str, Any] = None parameter
• _on_keep_alive_reconnected: Add data: Dict[str, Any] = None parameter
• _on_keep_alive_message: Change from message string to data dict, extract message via data.get("message", "")

# Before
async def _on_keep_alive_connected(self):
    ...

# After
async def _on_keep_alive_connected(self, data: Dict[str, Any] = None):
    ...

Fixes #43

Pull request overview

This PR fixes a critical bug where event handlers in AsyncPocketOptionClient had incorrect signatures, causing TypeError when called by ConnectionKeepAlive._emit_event(). The issue (#43) manifested as "takes 1 positional argument but 2 were given" errors because the handlers didn't accept the data parameter that _emit_event() always passes.

Key Changes:

• Updated three event handler signatures to accept a data: Dict[str, Any] = None parameter
• Modified _on_keep_alive_message to extract the message string from the data dictionary
• Added comprehensive test suite to verify the fix and prevent regression

The type hint should be Optional[Dict[str, Any]] instead of Dict[str, Any] since the default value is None. This properly indicates that the parameter can be either a dictionary or None.
