Integrate BACKBEAT SDK and resolve KACHING license validation

Major integrations and fixes:
- Added BACKBEAT SDK integration for P2P operation timing
- Implemented beat-aware status tracking for distributed operations
- Added Docker secrets support for secure license management
- Resolved KACHING license validation via HTTPS/TLS
- Updated docker-compose configuration for clean stack deployment
- Disabled rollback policies to prevent deployment failures
- Added license credential storage (CHORUS-DEV-MULTI-001)

Technical improvements:
- BACKBEAT P2P operation tracking with phase management
- Enhanced configuration system with file-based secrets
- Improved error handling for license validation
- Clean separation of KACHING and CHORUS deployment stacks

+// Package yaml is just an indirection to handle YAML deserialization.
+//
+// This package is just an indirection that allows the builder to override the
+// indirection with an alternative implementation of this package that uses
+// another implementation of YAML deserialization. This allows to not either not
+// use YAML deserialization at all, or to use another implementation than
+// [gopkg.in/yaml.v3] (for example for license compatibility reasons, see [PR #1120]).
+//
+// Alternative implementations are selected using build tags:
+//
+//   - testify_yaml_fail: [Unmarshal] always fails with an error
+//   - testify_yaml_custom: [Unmarshal] is a variable. Caller must initialize it
+//     before calling any of [github.com/stretchr/testify/assert.YAMLEq] or
+//     [github.com/stretchr/testify/assert.YAMLEqf].
+//
+// Usage:
+//
+//	go test -tags testify_yaml_fail
+//
+// You can check with "go list" which implementation is linked:
+//
+//	go list -f '{{.Imports}}' github.com/stretchr/testify/assert/yaml
+//	go list -tags testify_yaml_fail -f '{{.Imports}}' github.com/stretchr/testify/assert/yaml
+//	go list -tags testify_yaml_custom -f '{{.Imports}}' github.com/stretchr/testify/assert/yaml
