feat(destinations): openapi for Outpost queue types (SQS/PubSub/RabbitMQ reshape + Azure Service Bus, Kafka) + drop SNS (ENG-4130)

[RajatPawar]

Summary

Reshapes the message-queue destination OpenAPI schemas to match the final builder-facing contract now that message-queue destinations are reimplemented on Outpost (replacing Svix). Destination metadata/secrets are modeled as a single shared flat schema with per-type semantics documented in field descriptions (the existing repo convention); these edits add/remove named fields, update the type enum, and adjust the updateMask allowed-paths list.

Changes

sqs — metadata: queueUrl (required), endpointUrl (optional); no region. secrets: now uses awsKeyId (required), awsSecretKey (required), awsSessionToken (optional) instead of accessKeyId/secretAccessKey.

pubsub — metadata: projectId (required), topicId (required). secrets: credentials (required).

rabbitmq — metadata: serverUrl (required), exchange (required), tls (optional bool); removed routingKey. secrets: username (required), password (required); removed uri.

azureservicebus (new) — metadata: name (required). secrets: connectionString (required).

kafka (new) — metadata: brokers (required), topic (required), saslMechanism (required; enum plain / scram-sha-256 / scram-sha-512), tls (optional bool), partitionKeyTemplate (optional). secrets: username (required), password (required).

sns — removed entirely (dropped from the type enum and its topicArn metadata removed).

eventbridge, azureblob, gcs, warehouse types, webhook, slack, kinesis, s3 are untouched.

Final type enum

[webhook, kinesis, s3, slack, clickhouse, snowflake, bigquery, redshift, sqs, eventbridge, pubsub, rabbitmq, azureservicebus, kafka]

Files

• api/api.yaml — createDestination request body (enum + metadata + secrets), updateDestination updateMask list + nested metadata/secrets, Destination and DestinationWithSecrets response schemas
• api/generated/api.json, api/generated/api.bundled.json — regenerated via make gen

catalog/generated/catalog.json churn from generation was reverted to keep the diff focused on destinations.
