feat: improve build service with init container cleanup and dev tooling

[d4rkstar]

Major improvements to the build service and development environment:

Build Service Enhancements:

• Add wait logic for init container completion before resource cleanup
• Prevent race condition where ConfigMaps/Secrets deleted before pod reads them
• Add new KubeApiClient methods: get_pod() and wait_for_init_container_completion()
• Refactor cleanup into _cleanup_build_resources() helper method
• Add null check for jobs list to prevent iteration errors
• Fix Pylance type errors with proper type annotations (str | None)

Kubernetes API Client:

• Fix time module import (was importing datetime.time instead of time module)
• Add pod status monitoring and init container state tracking
• Add detailed logging for container lifecycle events
• Support timeout-based waiting with configurable durations

Development Environment:

• Add VSCode debug configuration with automatic port-forwarding
• Create start-port-forwards.sh script for registry and CouchDB
• Add tasks.json with Start/Stop Port Forwards tasks
• Update TaskfileDev.yml with setup-secret task for dev credentials
• Auto-setup registry-pull-secret-dev and REGISTRY_SECRET env var

Response Builder & Security:

• Improve response formatting and error handling
• Minor fixes to authorization decorators
