Rename types and cch fields

[chenyukang]

Maintain consistent naming styles.

[Copilot]

Pull request overview

This PR updates naming conventions across the CCH order status types and channel state_flags string representations to be consistent across Rust types, JSON-RPC types/docs, and e2e/tests.

Changes:

• Renamed CchOrderStatus variants (OutgoingSucceeded→OutgoingSuccess, Succeeded→Success) and updated state machine/actions/tests accordingly.
• Standardized RPC state_flags output/expectations to SCREAMING_SNAKE_CASE (e.g., COOPERATIVE, WAITING_COMMITMENT_CONFIRMATION).
• Updated JSON-RPC docs/schema helpers and Bruno e2e tests to match the new naming.

• define_rpc_flags deserialization now only accepts SCREAMING_SNAKE_CASE names separated by |. This is a breaking change from the previous behavior (PascalCase + comma-separated) and will reject any existing client input using the old format. Consider accepting both separators (, and |) and optionally mapping legacy PascalCase to the new SCREAMING_SNAKE_CASE during parsing to preserve backward compatibility.
