* fix(ec): pass per-volume data-shard count to the parity-shard split ShardsInfo.DeleteParityShards/MinusParityShards looped ids 10..13, assuming the fixed 10+4 layout. For a non-default ratio this splits data vs parity wrong — a wide ratio (12+4, 16+6) drops real data ids >= 10, which breaks ec.decode. They now take a dataShards argument (<= 0 falls back to DataShardsCount) and clear ids dataShards..MaxShardCount. ec.decode threads the data-shard count from collectEcNodeShardsInfo to both split call sites, and admin LogicalSize passes DataShardsCount. Also: EC cleanup now sets an explicit per-disk storage impact (-len(ShardIds)) instead of falling back to the TotalShardsCount constant, so freed-capacity accounting matches the shards actually removed. OSS is always 10+4, so behavior is unchanged here; this keeps the split ratio-correct and the API aligned with the enterprise per-volume override. Adds parity-split ratio tests. * ec: clear parity shards in one locked pass Address review: DeleteParityShards looped si.Delete, taking the lock once per id. shards is sorted by Id and shardBits is a bitmap, so mask off the high bits and truncate the sorted slice at the first parity id (binary search) under a single lock. Preserves the dataShards<=0 -> DataShardsCount default.
