✨ server: add card limit update handler

[aguxez]

Summary by CodeRabbit

• New Features

  • Added a card-limit case: approved cases can trigger automatic card limit updates (amount applied in cents, weekly frequency) by resolving related inquiry references and updating active cards.
  • Added a new KYC scope "cardLimit" and inquiry flow to create or resume card-limit inquiries.

• Bug Fixes / Reliability

  • Clear response codes and graceful handling for missing data or lookup failures; errors are captured without breaking the webhook.

• Tests

  • Extensive tests covering card-limit flows, ignored inquiries, edge cases, and failure modes.

• Chores

  • Added patch release metadata.

Summary of Changes

Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces a new server-side capability to automatically adjust user card limits based on approved cases from the Persona identity verification platform. By integrating a dedicated webhook handler, the system can now process specific Persona events, validate the incoming data, and programmatically update card limits through an external API, streamlining the process of managing user financial controls.

Highlights

• New Persona Webhook Handler: Implemented a new webhook handler for Persona events specifically designed to process 'card limit' cases. This handler will update card limits in the system based on approved Persona cases.
• Card Limit Update Logic: Added logic to extract the new card limit from approved Persona cases, retrieve associated credential and card information from the database, and then call an external service (updateCard in Panda) to apply the new limit.
• Enhanced Validation and Error Handling: Introduced new validation schemas for the 'card limit' case template and inquiry template. The handler includes robust error handling for scenarios like missing card limits, credentials, or active cards, and captures exceptions using Sentry.
• Comprehensive Test Coverage: Added extensive unit tests to cover various scenarios for the new card limit update handler, including successful updates, handling of declined cases, missing data, and API failures.

Changes

Cohort / File(s)	Summary
Changesets & Release \.changeset/clear-cobras-sip.md	New changeset declaring a patch release for @exactly/server with note "add card limit case update".
Persona Hook server/hooks/persona.ts	Added cardLimit payload schema branch and handler: Sentry op, short-circuit responses for non-Approved statuses, extract inquiry id, call getInquiryById, DB queries for credential and ACTIVE card, conditional panda.updateCard with amount = cardLimitUsd * 100, and error capture. Also updated ignored-template allowlist handling.
Persona Utilities server/utils/persona.ts	Added exports CARD_LIMIT_CASE_TEMPLATE, CARD_LIMIT_TEMPLATE, and getInquiryById(inquiryId) which performs Persona GET /inquiries/:id and validates presence of data.attributes["reference-id"].
KYC API server/api/kyc.ts	Extended POST body validation to accept scope: "cardLimit" and added control flow for creating/resuming/failing card-limit inquiries using CARD_LIMIT_TEMPLATE. GET query validation also allows "cardLimit".
Tests — Persona Hook server/test/hooks/persona.test.ts	Added comprehensive card limit case test suite, extended "with reference" tests, added mocks (e.g., persona.addDocument), updated invalid-payload expectations, and cleaned up cards rows in afterEach. Covers success, no-card, no-limit, no-credential, no-panda, updateCard failure, and ignored-template paths.
Tests — KYC API server/test/api/kyc.test.ts	Added cardLimit scope tests for POST flow: creating new inquiry, resuming valid statuses, rejecting terminal/failed statuses, unknown credential case, and forwarding redirectURI to createInquiry.
