feat(bindings/python): add behavior tests for conditional read/write

The Python bindings support conditional headers (if_match, if_none_match)
on read and write operations, but there were no behavior tests covering
these important HTTP semantics.

This commit adds focused behavior tests for both sync and async:
- read with if_match: succeeds on matching etag, fails on mismatch
- read with if_none_match: fails on matching etag, succeeds on mismatch
- write with if_match: overwrites on matching etag, fails on mismatch
- write with if_none_match: succeeds when file absent, fails when present

Tests gracefully skip when the backend does not return etags.
