feat(studio): support deployment resource configuration

[evanlowe]

Summary

• add a Resource Configuration section before environment variables on the final deployment page
• support automatic creation, custom names, and existing-resource selection for TOS, CR, and CodePipeline
• show generated automatic resource names and provide searchable existing-resource selectors with infinite-scroll pagination
• persist resource metadata in Runtime tags so in-place updates reuse the original resources while keeping resource controls hidden during updates
• keep legacy Runtime updates compatible when resource tags are absent
• support both Volcengine and BytePlus resource APIs and credential environments
• preserve original deployment and resource-loading errors while redacting credentials
• align resource fields and remove the gray fill from deployment configuration cards

Dependency

Requires agentkit-sdk-python#163 for resource-listing APIs and custom build-resource handling.

Testing

• pre-commit hooks: Ruff check, Ruff format, and gitleaks
• frontend tests: 424 passed
• frontend production build: passed
• full Python test suite: 1277 passed, 6 skipped, 6 subtests passed
• local provider deployment matrix: 27 Volcengine combinations and 27 BytePlus combinations passed
• real Volcengine deployments verified with existing resources, named TOS creation, named and automatic CodePipeline creation, automatic TOS selection, and Runtime in-place update
• real BytePlus deployment verified with existing TOS, CR, and CodePipeline resources, followed by Runtime version 1 to 2 in-place update using the same Runtime ID and resources
• temporary BytePlus Runtime was removed and verified absent after testing

Known limits

• the Volcengine validation account had exhausted CR repository and Micro instance quotas, so automatic and named CR creation were rejected by the cloud service; those request paths are covered by provider tests
• the cloud-hosted Studio IAM replay still requires an authorized Identity login; direct real-cloud resource validation completed successfully
