[v3-3-test] Fix Java coordinator rejecting macOS dual-stack loopback 
connections (#68960) (#68973)

## Why

On macOS the task JVM's dual-stack loopback connection is reported by psutil in 
the IPv4-compatible form (`::127.0.0.1`), which the coordinator's ownership 
check did not normalize (only the IPv4-mapped `::ffff:127.0.0.1` form was), so 
every Java task was rejected with "process exited with 1 before connecting".

## What

- Canonicalize IPv4-compatible IPv6 (`::a.b.c.d`) to plain IPv4 in 
`_socket_address`, excluding `::` and `::1`, alongside the existing IPv4-mapped 
handling.
- Add `test_matches_dual_stack_ipv4_compatible_connection` regression test.
(cherry picked from commit a2f8a7ab39d55300531edba310e0453bb2546cf3)
