Server-Side Filtering in `conversations.list()` Method

[Fabri]

Feature Request:

Enhance the conversations.list() function to support server-side time-based filtering and provide sorting by the most recent messages.

Current Behavior:

The function fetches all conversations and applies filters like startTime and endTime only after loading, which is not efficient.

Desired Features:

1. Server-Side Time Filtering: Allow filtering conversations by startTime and endTime on the server before fetching to the client.
2. Recent Message Sorting: Enable sorting by the timestamp of the most recent message while respecting protocol privacy.
