Resolve CI timeouts and miscellaneous updates for 2026-W35

[khaeru]

Around 2026-05-31 (see here), CI jobs began to fail by timing out at the 6-hour limit. Previously (e.g. here) all jobs ran in 5–10 minutes.

This PR and branch are to diagnose and resolve the issue.

Actual steps:

• Add pytest-timeout configuration.
  • Limit all tests
• Identified one case of .test_ckan.TestClient.test_call_action_getattr() as
  timing out. Specifically, the case that calls the tag_list CKAN API endpoint on the TDCI CKAN 'dev' instance times out. I did not investigate whether this happens because of slowness on the server side; a very large response (that never completes?); or some client-side issue in processing a complete response. The test case is skipped.
• ATO provider:

  • Update hashes for known files.

  • Update the Zenodo record (DOI 10.5281/zenodo.14913729) with newer files.

  • Handle changes in the file format. Previously, the footer of each sheet contained 2 rows/cells like:

    Developed with the support of: Asian Development Bank and Asian Infrastructure Investment Bank
    See terms of use at https://asiantransportoutlook.com/termsofservice
    

    Recent files have instead:

    The Asian Transport Observatory (ATO) is developed with the support of the Asian Development Bank (ADB) and the Asian Infrastructure Investment Bank (AIIB).
    Activities in the Pacific Island Countries are additionally supported by the World Bank.
    See terms of use at https://asiantransportobservatory.org/termsofservice
    

    Now, instead of removing a fixed number of footer rows, a regular expression is added to match and discard these entries. This regex handles both the old and new style.

Some ideas that were not tried in this PR:

• Ensure data retrieval/caching is not duplicated across pytest-xdist workers.
• Separate slow-running checks into separate jobs; or only run them on some jobs.
