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

+# multiaddr format
+A validation checker for multiaddrs. Some basic validators for common address
+types are provided, but creating your own combinations is easy.
+
+Usage:
+```go
+a, _ := ma.NewMultiaddr("/ip4/5.2.67.3/tcp/1708")
+TCP.Matches(a) // returns true
+```
+
+Making your own validators is easy, for example, the `Reliable` multiaddr is
+defined as follows:
+
+```go
+// Define IP as either ipv4 or ipv6
+var IP = Or(Base(ma.P_IP4), Base(ma.P_IP6))
+
+// Define TCP as 'tcp' on top of either ipv4 or ipv6
+var TCP = And(IP, Base(ma.P_TCP))
+
+// Define UDP as 'udp' on top of either ipv4 or ipv6
+var UDP = And(IP, Base(ma.P_UDP))
+
+// Define UTP as 'utp' on top of udp (on top of ipv4 or ipv6)
+var UTP = And(UDP, Base(ma.P_UTP))
+
+// Now define a Reliable transport as either tcp or utp
+var Reliable = Or(TCP, UTP)
+
+// From here, we can easily define multiaddrs for protocols that can run on top
+// of any 'reliable' transport (such as ipfs)
+```
+
+NOTE: the above patterns are already implemented in package
