torlando-tech 4c75f9d080 fix: remove redundant local imports causing telemetry callback failure 
The `import json` statements inside _on_lxmf_delivery() caused Python
to treat `json` as a local variable throughout the function scope.
This resulted in "cannot access local variable 'json'" errors when
json.dumps() was called before those imports ran.

Since json and time are already imported at module level, the local
imports were unnecessary and harmful.
