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 temperrcatcher provides a TempErrCatcher object,
+// which implements simple error-retrying functionality.
+// It is meant to be used with things like net.Lister.Accept:
+//
+//   import (
+//     tec "github.com/jbenet/go-temp-err-catcher"
+//   )
+//
+//   func listen(listener net.Listener) {
+//     var c tec.TempErrCatcher
+//
+//     for {
+//       conn, err := listener.Accept()
+//       if err != nil && c.IsTemporary(c) {
+//         continue
+//       }
+//       return conn, err
+//     }
+//   }
+//
+// You can make your errors implement `Temporary`:
+//
+//   type errTemp struct {
+//     e error
+//   }
+//
+//   func (e errTemp) Temporary() bool {
+//     return true
+//   }
+//
+//   func (e errTemp) Error() string {
+//     return e.e.Error()
+//   }
+//
+//   err := errors.New("beep boop")
+//   var c tec.TempErrCatcher
+//   c.IsTemporary(err)              // false
+//   c.IsTemporary(errTemp{err}) // true
+//
+// Or just use `ErrTemp`:
+//
+//   err := errors.New("beep boop")
+//   var c tec.TempErrCatcher
+//   c.IsTemporary(err)              // false
+//   c.IsTemporary(tec.ErrTemp{err}) // true
+//
+//
+// You can also define an `IsTemp` function to classify errors:
+//
+//   var ErrSkip = errors.New("this should be skipped")
+//   var ErrNotSkip = errors.New("this should not be skipped")
+//
+//   var c tec.TempErrCatcher
+//   c.IsTemp = func(e error) bool {
+//     return e == ErrSkip
+//   }
+//
+//   c.IsTemporary(ErrSkip) // true
+//   c.IsTemporary(ErrNotSkip) // false
+//   c.IsTemporary(ErrTemp) // false! no longer accepts Temporary()
+//
