fix(ack-pay): reject empty payment request and option fields

[kutluhaneth46]

Summary

• Payment option id / currency / recipient, payment request id, and receipt claim paymentOptionId previously accepted empty strings via bare v.string() / z.string().
• Other fields already reject invalid values (e.g. amount), so blank identifiers were an inconsistency rather than an intentional allowance.
• Introduce a shared non-empty string helper in both Valibot and Zod schemas, with parity tests.

This is a clean rebase of the same fix attempted in #183 (currently conflicting with main).

Test plan

• pnpm --filter @agentcommercekit/ack-pay exec vitest run src/schemas/schemas.test.ts
• Empty id / currency / recipient on a payment option are rejected by both schemas
• Empty payment request id is rejected by both schemas

AI usage disclosure

AI-assisted with Cursor for identifying the empty-string acceptance, implementing the shared non-empty string validators, tests, and changeset. I reviewed the dual-schema change and understand why these fields need length checks at the schema gate used by HTTP 402 bodies and token verification.

Summary by CodeRabbit

• Bug Fixes

  • Payment requests and options now reject empty identifiers, currencies, and recipient values.
  • Payment receipt claims now reject empty payment option identifiers.
  • Validation behavior is consistent across supported schema formats, helping prevent incomplete payment data from being accepted.

• Tests

  • Added coverage confirming empty required fields are rejected across payment requests, options, and receipt claims.

Thank you for the contribution. This duplicates #183, which was opened first and is in review. Contributing to that PR is more helpful than a parallel version. Closing as a duplicate.
