fix(identity): align UCPPaymentHandler config emission with Node optional convention

Two cross-language parity fixes:

1. UCPPaymentHandler.to_dict() now omits the `config` key when empty. Node's
   `UCPPaymentHandler.config` is a TypeScript optional property and
   `buildUCPProfile` passes the array verbatim, so a Node caller writing
   `{ name: 'tempo' }` shipped a wire profile WITHOUT `config`. Python was
   force-emitting `config: {}` for that same input, producing different
   canonical bytes between SDKs for the same logical input. Explicit
   `config={}` is semantically identical to absent and follows the same
   omit rule.

2. Standalone int-boundary fixture script now uses build_ucp_profile(extras=...)
   instead of hand-building a profile dict with a top-level `extras` key.
   The orchestrator was already correct; the standalone version (used for
   one-off debug regen of a single fixture) was producing canonical bytes
   with a nested `extras` block while the orchestrator-produced fixture was
   flat. Mirrors how the data-driven-claims and typed-claims standalone
   scripts already work.

Cross-lang fixture corpus regenerated; new tests cover the omit behavior.
