* fix(audit): resolve AB-BA lock-order deadlock between registry and stream_cancellers (backlog#961)
`AuditSystem::runtime_status_snapshot` acquired `stream_cancellers.read()`
before `registry.lock()`, while every other path that holds both locks
(`clear_runtime_targets`, `AuditRuntimeFacade::replace_targets`) acquires
`registry` first. Under concurrency (e.g. admin status polling racing a
config reload) this AB-BA ordering could deadlock the whole audit control
plane with no self-recovery.
Reorder `runtime_status_snapshot` to acquire `registry` before
`stream_cancellers`, unifying the global lock order to
`registry -> stream_cancellers` across all double-lock paths, and add a
multi-threaded regression test that hammers both critical sections with a
timeout guard to fail fast if the ordering regresses.

* docs(audit): reword AB-BA to ABBA to satisfy typos check (backlog#961)
Avoid setting AuditSystemState::Starting when target list is empty.
Now checks target availability before state transition, keeping the
system in Stopped state if no enabled targets are found.
- Check targets.is_empty() before setting Starting state
- Return early with Ok(()) when no targets exist
- Maintain consistent state machine behavior
- Prevent transient "Starting" state with no actual targets
Resolves issue where audit system would incorrectly enter Starting
state even when configuration contained no enabled targets.

* feat(storage): refactor audit and notification with OperationHelper
This commit introduces a significant refactoring of the audit logging and event notification mechanisms within `ecfs.rs`.
The core of this change is the new `OperationHelper` struct, which encapsulates and simplifies the logic for both concerns. It replaces the previous `AuditHelper` and manual event dispatching.
Key improvements include:
- **Unified Handling**: `OperationHelper` manages both audit and notification builders, providing a single, consistent entry point for S3 operations.
- **RAII for Automation**: By leveraging the `Drop` trait, the helper automatically dispatches logs and notifications when it goes out of scope. This simplifies S3 method implementations and ensures cleanup even on early returns.
- **Fluent API**: A builder-like pattern with methods such as `.object()`, `.version_id()`, and `.suppress_event()` makes the code more readable and expressive.
- **Context-Aware Logic**: The helper's `.complete()` method intelligently populates log details based on the operation's `S3Result` and only triggers notifications on success.
- **Modular Design**: All helper logic is now isolated in `rustfs/src/storage/helper.rs`, improving separation of concerns and making `ecfs.rs` cleaner.
This refactoring significantly enhances code clarity, reduces boilerplate, and improves the robustness of logging and notification handling across the storage layer.
