Data Streams: update ha mode behavior for rust

[dev-dist]

This pull request updates the Data Streams SDK documentation to clarify and improve guidance on enabling High Availability (HA) mode for WebSocket connections. The changes focus on simplifying HA configuration, emphasizing automatic origin discovery from a single endpoint, and updating example code and explanations throughout the documentation.

Key documentation improvements:

High Availability Mode Clarification & Usage:

• Updated HA mode documentation to explain that enabling WebSocketHighAvailability::Enabled with a single WebSocket URL allows the SDK to automatically discover and connect to multiple origins for improved reliability. This replaces the previous method of manually specifying multiple endpoints. [1] [2]
• Added detailed descriptions of HA mode behavior, including origin discovery, deduplication of reports, partial and full reconnects, and the requirement that HA mode is only available on mainnet endpoints. [1] [2]

Code Example & API Reference Updates:

• Revised all Rust code samples to use a single WebSocket URL when enabling HA mode, and updated method descriptions to reflect the new automatic origin discovery mechanism. [1] [2] [3] [4]
• Updated tutorials and usage examples to demonstrate the new HA configuration pattern, including explanatory notes on automatic origin discovery. [1] [2] [3] [4]

General Documentation Consistency:

• Replaced outdated references to manual multi-endpoint configuration with links to the improved HA mode documentation and clarified language throughout. [1] [2]
• Updated feature lists and overviews to refer to "WebSocket streaming with HA mode" instead of "Multiple WebSocket endpoints (HA)" for clarity. [1] [2]

These changes make it easier for developers to enable and understand HA mode in the Data Streams SDK, reducing configuration complexity and improving reliability in production environments.
