Describe the bug

When importing a .json file containing configuration secrets via drag-and-drop or the import function, only top-level keys are imported successfully. Nested JSON objects are omitted from the import process.
For example, given the following JSON structure:

{
  "dbic_schema": "Example::Controller::Schema",
  "salt": "some salt",
  "environment": "development",
  "hypnotoad": {
    "workers": 2,
    "proxy": 1,
    "listen": ["http://*:8080"],
    "pid_file": "/var/run/example.pid"
  }
}

Only the first three top-level keys (dbic_schema, salt, and environment) are imported. The nested hypnotoad object and its contents are completely omitted.

Expected behavior

All keys and values should be imported from the JSON file, including nested objects and arrays, possibly in dot notation, as long as the JSON structure is valid.

Screenshots

Platform you are having the issue on:

eu.infisical.com, version bd29b3c

Additional context

This issue affects any JSON file containing nested objects or arrays. The import process appears to flatten or truncate the data structure instead of preserving the full hierarchy.
