fix(heal): fall back to set-wide format for directory-backed replacement targets

Since #7018 `renew_disk` routes an unformatted local endpoint through the automatic replacement heal, which requires the target to be an independently mounted disk. Directory-backed deployments (the operator set `RUSTFS_UNSAFE_BYPASS_DISK_CHECK`, which the startup disk-independence check already requires for endpoints sharing a device) can never pass that admission, so a runtime-wiped or replaced directory disk stayed unformatted forever: the heal task failed with "replacement target is not a stable mounted disk" and the auto-scan kept deferring the endpoint. This broke the Issue #1533 contract and the `heal_erasure_disk_rebuild_test` lane on main since 2026-09-02.

When the disk-check bypass is set and the replacement target fails admission, the erasure-set heal now logs a warning and downgrades to the ordinary set-wide `heal_format` path that predated replacement admission, and the auto-scan no longer defers such endpoints. The mount admission itself is unchanged and still cannot be bypassed by any environment variable; deployments without the bypass keep failing closed.

The endpoint-blackhole heal scenario now probes whether `iptables` can read the OUTPUT chain and logs an explicit skip when the host lacks `CAP_NET_ADMIN` (containerised runners report "Permission denied" from the nf_tables backend even under sudo); `RUSTFS_E2E_REQUIRE_NET_FAULT_INJECTION=1` turns that into a failure for lanes that provision the capability. The CI full-gate job surfaces the missing capability as a workflow warning, and the runtime-wipe fixture retries `remove_dir_all` on the listing race macOS surfaces as `DirectoryNotEmpty`.

Refs rustfs/backlog#2357.

## Troubleshooting
**Endpoint blackhole scenario skipped** — `heal_erasure_disk_rebuild_test::tests::test_cluster_root_heal_recovers_after_target_endpoint_blackhole` installs a loopback `iptables` DROP rule and therefore needs `CAP_NET_ADMIN` (root or passwordless `sudo -n iptables`). A host where `iptables` is missing or cannot read the OUTPUT chain (typical inside an unprivileged container, where the nf_tables backend reports "Permission denied" even under `sudo`) logs a `heal_interruption_skipped` warning and returns without exercising heal. Set `RUSTFS_E2E_REQUIRE_NET_FAULT_INJECTION=1` on lanes that do provision the capability so a broken runner fails instead of skipping.
