🐛 Bug: View count no longer working

### Description

View count was displayed next to the relative time but the API we used (img.shields.io) has retired showing YouTube stats.

### Steps to reproduce

Effects all cards

```
=========================== short test summary info ============================
FAILED tests/test_app.py::test_request_valid_params - assert None is not None
FAILED tests/test_app.py::test_request_right_to_left - assert None is not None
FAILED tests/test_utils.py::test_fetch_views - AssertionError: assert None
========================= 3 failed, 26 passed in 3.30s =========================

```

### Screenshots

Views no longer showing:

Views used to be shown before the publish date:

Start by running the failing tests listed in tests/test_app.py and tests/test_utils.py, then inspect the view-fetching path that calls the retired img.shields.io YouTube stats API. Restore view counts for all cards and make the three reported tests pass without breaking the 26 passing tests.
