DEV-14971: Python SDK storage-service compatibility unit tests

[sihrc]

Summary

• Adds unit tests verifying the Python SDK is fully compatible with storage-service response shapes (the Rainbow replacement)
• Audit result: no client patches needed — storage-service /files/store returns path/name/upload_type matching exactly what UploadDocument expects; indico-file:// URI handling is unchanged
• Tests cover UploadDocument, CreateStorageURLs, and RetrieveStorageObject against the LegacyUploadResponseItem response shape

Test plan

• test_upload_document_posts_to_storage_files_store — confirms POST target path
• test_upload_document_processes_path_name_upload_type — confirms response field mapping
• test_upload_document_handles_multiple_files — multi-file upload batch
• test_create_storage_urls_builds_indico_file_uris — URI construction from response
• test_create_storage_urls_round_trips_through_retrieve — round-trip URI → path
• test_retrieve_storage_object_strips_indico_file_scheme — path extraction
• test_retrieve_storage_object_accepts_dict_with_url_key — dict input variant
• test_retrieve_storage_object_fetches_content — end-to-end GET with mock response

All 8 tests pass. No network required.

Note

Medium Risk
Updates the dynamic versioning regex used for packaging, which can affect release/version resolution if the new tag-matching behavior is incorrect. Other changes are test-only and low risk.

Overview
Adds unit tests that mock HTTP calls to verify the SDK’s storage queries (UploadDocument, CreateStorageURLs, RetrieveStorageObject) remain compatible with storage-service response shapes and indico-file:// URI/path handling.

Updates uv-dynamic-versioning tag matching to accept dotted PEP 440-style suffixes (e.g. 7.9.0.post1) in addition to hyphenated prereleases, and adds a focused test to lock in the new regex behavior; notes the change in CHANGES.txt.

Storage migration freeze checkpoint (2026-04-15): PR remains under NOT MERGE policy, but is still failing from 2026-04-12. Requesting a CI rerun to refresh review evidence while keeping this PR unmerged.

[sihrc]

Correction: failing check context is publish_python_sdk-unit_tests. Please rerun this CI context for fresh freeze-period validation signal (PR remains NOT MERGE).

[sihrc]

Escalation: check context publish_python_sdk-unit_tests is still stale (last started 2026-04-12T00:02:54Z) after rerun request. Requesting CI run owners/maintainers to trigger a fresh Harness run so we can refresh freeze-period validation evidence. PR remains NOT MERGE.

Please trigger/own a fresh run for freeze-period validation evidence. PR remains NOT MERGE.
