perf(ecstore): per-bucket durability tier overrides (HP-5 phase 2)

Let a bucket override the process-wide RUSTFS_DURABILITY_MODE with its own
strict/relaxed/none tier, stored as a durability.json extension entry in the
bucket metadata file and resolved at commit points via effective_durability.
System-critical buckets (.rustfs.sys, .minio.sys) can never carry an override
and stay pinned to strict; the legacy full-off switch keeps its historical
semantics and per-bucket overrides do not apply under it. Overrides are
published and cleared through the existing bucket metadata cache-invalidation
path, and an admin GET/PUT handler exposes the configuration. Default behavior
is unchanged: with no override a bucket follows the global mode, which defaults
to strict and stays byte-for-byte identical to before.
