feat: upgrade nodriver from 0.39 to 0.47 (#635)

## ℹ️ Description
Upgrade nodriver dependency from pinned version 0.39.0 to latest 0.47.0
to resolve browser startup issues and JavaScript evaluation problems
that affected versions 0.40-0.44.

- Link to the related issue(s): Resolves nodriver compatibility issues
- This upgrade addresses browser startup problems and window.BelenConf
evaluation failures that were blocking the use of newer nodriver
versions.

## 📋 Changes Summary

- Updated nodriver dependency from pinned 0.39.0 to >=0.47.0 in
pyproject.toml
- Fixed RemoteObject handling in web_execute method for nodriver 0.47
compatibility
- Added comprehensive BelenConf test fixture with real production data
structure
- Added integration test to validate window.BelenConf evaluation works
correctly
- Added German translation for new error message
- Replaced real user data with privacy-safe dummy data in test fixtures

### 🔧 Type Safety Improvements

**Added explicit `str()` conversions to resolve type inference issues:**

The comprehensive BelenConf test fixture contains deeply nested data
structures that caused pyright's type checker to infer complex
dictionary types throughout the codebase. To ensure type safety and
prevent runtime errors, I added explicit `str()` conversions in key
locations:

- **CSRF tokens**: `str(csrf_token)` - Ensures CSRF tokens are treated
as strings
- **Special attributes**: `str(special_attribute_value)` - Converts
special attribute values to strings
- **DOM attributes**: `str(special_attr_elem.attrs.id)` - Ensures
element IDs are strings
- **URL handling**: `str(current_img_url)` and `str(href_attributes)` -
Converts URLs and href attributes to strings
- **Price values**: `str(ad_cfg.price)` - Ensures price values are
strings

These conversions are defensive programming measures that ensure
backward compatibility and prevent type-related runtime errors, even if
the underlying data structures change in the future.

### ⚙️ Type of Change
- [x] ✨ New feature (adds new functionality without breaking existing
usage)
- [ ] 🐞 Bug fix (non-breaking change which fixes an issue)
- [ ] 💥 Breaking change (changes that might break existing user setups,
scripts, or configurations)
