fix(auth): strip unsupported Stripe timestamps

[zbeyens]

Summary

• Strip auth createdAt and updatedAt writes when the target auth/plugin table does not define those fields.
• Add regression coverage for Stripe-style subscription tables that omit timestamp fields.
• Wire @better-auth/stripe into example/ and regenerate auth schema, proving the generated subscription table has no createdAt/updatedAt.
• Refresh Expo fixture snapshots for the upstream Expo 55.0.17 template drift found by bun check.

Verification

• bun run schema:sync in example/
• bun run check in example/
• bun test packages/kitcn/src/auth/create-api.test.ts packages/kitcn/src/auth/create-api.factory.test.ts
• bun typecheck
• bun --cwd packages/kitcn build
• bun run fixtures:sync
• bun run fixtures:check
• bun check
