Summary

Listing a bucket with a prefix that contains a word like location, versioning, uploads, delete or tagging (for example .../table/geocoded_locations/) no longer returns the wrong answer. The proxy now recognises these sub-resources only when they are real query parameters, so such listings return the object list. This fixed Scylla Manager restores failing with "file ... is not present in listed versioned files" for main.geocoded_locations.

After merge, the s3proxy image tag in argocd-system (src/services/s3proxy-python, currently 2026.8.1) needs bumping to the release containing this.

Changes

• Request routing parses the query string and matches on parameter names instead of searching the raw string.
• Metrics operation naming uses the same parameter-name matching, so these listings are labelled correctly.
• Added a unit test covering prefixes that contain each sub-resource name, for V1 and V2 listings.
