fix(types): make id and status optional in ResponseOutputMessageParam

When sending a client-authored assistant message via the Responses API
(e.g. replayed from storage, edited, or produced by other code), the
caller has no OpenAI message id or status. Previously the type system
required both fields, forcing developers to fabricate fake values or
use `# type: ignore`.

This change makes `id` and `status` Optional in both
`ResponseOutputMessageParam` and `BetaResponseOutputMessageParam`,
consistent with other input item types (e.g. `ComputerCallOutput`,
`FunctionCallOutput`, `ShellCall`) which already use `Optional[str]`
for these fields.

Fixes #3544
