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

+
+A highly performant unique identifier generator.
+
+## Installation
+
+Use the `go` command:
+
+	$ go get github.com/nats-io/nuid
+
+## Basic Usage
+```go
+
+// Utilize the global locked instance
+nuid := nuid.Next()
+
+// Create an instance, these are not locked.
+n := nuid.New()
+nuid = n.Next()
+
+// Generate a new crypto/rand seeded prefix.
+// Generally not needed, happens automatically.
+n.RandomizePrefix()
+```
+
+## Performance
+NUID needs to be very fast to generate and be truly unique, all while being entropy pool friendly.
+NUID uses 12 bytes of crypto generated data (entropy draining), and 10 bytes of pseudo-random
+sequential data that increments with a pseudo-random increment.
+
+Total length of a NUID string is 22 bytes of base 62 ascii text, so 62^22 or
+2707803647802660400290261537185326956544 possibilities.
+
+NUID can generate identifiers as fast as 60ns, or ~16 million per second. There is an associated
+benchmark you can use to test performance on your own hardware.
