Zhengchao An 19c7529d88 refactor(ecstore): migrate data movement backpressure to shared ForegroundPressure (#6779)
refactor(ecstore): use shared ForegroundPressure for data movement

The data movement backpressure module carried its own byte-identical copy of ForegroundPressure, its reason() label mapping, and the foreground utilization computation. rustfs-concurrency now owns that logic as workload::ForegroundPressure and workload::foreground_pressure, so the local copy was a cross-crate synchronization point that could silently drift from the heal-side and admission-side behavior.

Delete the local type and computation and call the shared function instead. The call site keeps what is specific to data movement: the config.enabled short circuit, the optional provider unwrap, and the read/write threshold percentages read from DataMovementBackpressureConfig. The reason() labels emitted into the rustfs_data_movement_backpressure_total metric and the data_movement_backpressure log event are unchanged, as are the existing tests and their assertions.
