fix: resolve nodriver 0.47+ RemoteObject compatibility issues (#645)

## ℹ️ Description
*Provide a concise summary of the changes introduced in this pull
request.*

- Link to the related issue(s): #644
- Describe the motivation and context for this change.

This PR resolves compatibility issues with nodriver 0.47+ where
page.evaluate() returns RemoteObject instances that need special
handling for proper conversion to Python objects. The update introduced
breaking changes in how JavaScript evaluation results are returned,
causing TypeError: [RemoteObject] object is not subscriptable errors.

## 📋 Changes Summary

- Fixed TypeError: [RemoteObject] object is not subscriptable in
web_request() method
- Added comprehensive RemoteObject conversion logic with
_convert_remote_object_result()
- Added _convert_remote_object_dict() for recursive nested structure
conversion
- Fixed price field concatenation issue in MODIFY mode by explicit field
clearing
- Updated web_sleep() to accept integer milliseconds instead of float
seconds
- Updated German translations for new log messages
- Fixed linting issues (E711, E712) in test assertions
