Keep the mask-interpretation logic out of the Sync service handlers. The
`BlockMask` strategy and its path parsing now live in `masking.rs` next to
`apply_mask`, with a module doc explaining when each applies: `apply_mask` is a
post-hoc JSON projection for low-volume Query responses, `BlockMask` is a
source-level projection for the high-volume Sync streams. The handlers only
extract the paths and consult the flags while building the version-specific
`AnyChainBlock`.

  When a DecrementTx was applied on-chain before the head was closed
  (snapshotVersion != openVersion), partialFanout passed fullUTxO to
  buildAndVerifyAccumulator. But the closed datum's accumulatorCommitment
  was built from utxoForProof (snapshot UTxO including the decommit set),
  so the check always failed with StaleChainState, leaving the head stuck.

  Separate the accumulator proof input from the distribution set by adding
  a proofUTxO parameter to partialFanout and findFittingFanoutTx. The
  FanoutTx call site now passes utxoForProof as proofUTxO so it matches
  what the closed datum was committed to, while fullUTxO (the actual
  distribution set) is used unchanged for fanout outputs.
