feat(rpc): bind canonical body digest into internode mutating disk RPC signatures (#5234)

* feat(rpc): bind canonical body digest into internode mutating disk RPC signatures

Binds a domain-separated, length-prefixed canonical request-body digest into the
v2 HMAC signature scope for every mutating NodeService disk RPC, so an on-path
attacker on the default-plaintext internode channel can no longer tamper with a
mutation payload (or strip the msgpack `_bin` field to force the JSON fallback
decode) without invalidating the signature.

Covers 13 mutating disk RPCs: RenameData, DeleteVersion, DeleteVersions,
WriteMetadata, UpdateMetadata, WriteAll, Delete, DeletePaths, RenameFile,
RenamePart, DeleteVolume, MakeVolume, MakeVolumes. The digest covers both the
msgpack `_bin` payloads and their JSON compatibility copies. Gated fail-open by
default (RUSTFS_INTERNODE_RPC_BODY_DIGEST_STRICT) with a convergence counter, so
rolling upgrades are byte-for-byte unaffected; the replay-cache capacity is now
configurable and overflow fails closed with a metric.

* fix(rpc): satisfy architecture-migration compat-marker guard

Put the removal condition on the RUSTFS_COMPAT_TODO marker line itself, and
stop backticking env-var/metric names in the cleanup-register entry so the
guard's id extractor only sees the task-id.
