Add OpenAI requests card for Laravel Pulse

[gehrisandro]

This PR adds a Recorder and Card to integrate in a Laravel Pulse Dashboard.

The card supports two metrics:

• Requests per user: Shows the number of requests per user.
• Requests per endpoint: Shows the number of requests per endpoint.

<livewire:openai.pulse.requests />

If you want to be specific about the metric to show, you can pass it as type:

<livewire:openai.pulse.requests type="endpoint" />

<livewire:openai.pulse.requests type="user" />

TODOs:

• [ ] Add tests for Recorder and Livewire card

This PR depends on the event dispatching added here.

Card without type specified (type is selectable):

Card with type="user":

Card with type="endpoint":
