feat(audience): warn and drop identify()/alias() calls with a malformed passport id

[nattb8]

Summary

Studios sometimes call identify() or alias() with identityType: 'passport' but pass their own internal user id instead of a real Passport id, and today nothing catches it, so bad data silently flows into the audience pipeline. This rejects the call (no event sent, userId untouched) and warns unconditionally (not gated behind debug) when the id doesn't match the shape Passport actually issues (connection|id or a bare UUID), so studios see the mistake immediately during local testing instead of finding it in the data warehouse later.

Test plan

• Unit tests for isPassportIdValid (core) covering valid pipe-form ids, valid UUIDs, whitespace padding, and invalid shapes
• Unit tests for identify()/alias(): malformed passport id warns and drops the call; warning fires without debug enabled; valid ids and non-passport identity types never warn
• Unit tests confirming a whitespace-padded valid passport id is stored/sent trimmed, not with the padding intact (the id that's validated and the id that's stored/sent must match)
• Sample-app UI affordance ("Fill invalid Passport ID example") and a fix so the sample app's success/drop mirroring reflects the real SDK outcome instead of always showing "ok"
• pnpm jest passes for packages/audience/core and packages/audience/sdk
• eslint passes on all changed files
• tsc --noEmit passes for packages/audience/sdk
