test: cover empty webhook list for creators with no registered webhooks (#551)

[CodingAngel1]

Summary

Closes #551

This PR adds an integration test to verify that GET /api/v1/creators/:id/webhooks returns 200 OK with an empty array ([]) when a creator exists but has not registered any webhooks.

The current implementation is already correct. The listWebhooksHandler in src/modules/webhooks/webhook.controllers.ts delegates to webhookService.listWebhooks, which returns an empty array when no matching webhook records are found. This change adds automated test coverage to ensure that behavior remains consistent over time.

Scope

The new integration test:

• Creates a valid creator (User → StellarWallet → CreatorProfile) without registering any webhooks.

• Sends an authenticated request to GET /api/v1/creators/:id/webhooks using wallet-signed headers generated from the creator's Stellar keypair.

• Verifies that the endpoint returns:

  • HTTP 200 OK

  • success: true

  • data: []

Files Changed

File | Description -- | -- src/modules/webhooks/webhook.integration.test.ts | Adds a new integration test covering the "creator with no webhooks" scenario.

Verification

The following checks were executed locally:

docker compose up -d postgres
DATABASE_URL=postgresql://postgres:postgres@localhost:5432/accesslayer 

pnpm exec prisma db push --force-reset --skip-generate
pnpm exec prisma generate
DATABASE_URL=postgresql://postgres:postgres@localhost:5432/accesslayer 

pnpm jest src/modules/webhooks/webhook.integration.test.ts -t "#551" --runInBand
pnpm exec tsc --noEmit

All commands completed successfully. The new #551 integration test passed, and tsc --noEmit exited without errors.

Risk Assessment

Low risk.

This is a test-only change. No production code or application behavior has been modified.

Out of Scope

This PR does not address existing integration tests that use non-numeric creator IDs (for example, "webhook-test-creator-id"), which may fail the current parseCreatorId validation. Those pre-existing issues are unrelated to this change and will be handled separately.
