[F34 evidence] dump WCF binary-header dictionary for AddMonitoredItems
Extends tests/add_monitored_items_request_capture.rs with a manual
binary-header walk that prints every pre-interned string + its wire
id. The captured request's binary header pre-declares **23 strings**
covering the entire DataContract field set:

  wire-id  1  http://ASB.IDataV2:addMonitoredItemsIn
  wire-id  3  AddMonitoredItemsRequest
  wire-id  5  SubscriptionId
  wire-id  7  Items
  wire-id  9  http://schemas.datacontract.org/.../ASBIDataV2Contract
  wire-id 11  MonitoredItem
  wire-id 13  activeField
  wire-id 15  activeFieldSpecified
  wire-id 17  bufferedField
  wire-id 19  itemField
  wire-id 21  contextNameField
  wire-id 23  idField
  wire-id 25  idFieldSpecified
  wire-id 27  nameField
  wire-id 29  referenceTypeField
  wire-id 31  typeField
  wire-id 33  sampleIntervalField
  wire-id 35  timeDeadbandField
  wire-id 37  timeDeadbandFieldSpecified
  wire-id 39  userDataField
  wire-id 41  lengthField
  wire-id 43  payloadField
  wire-id 45  valueDeadbandField

That gives F34's binary-builder rewrite the exact dict-id mapping
to target — every MonitoredItem child can be emitted as a
DictionaryStatic(odd-id) reference instead of an inline string,
matching WCF's compression. The "RequireId" mystery from the
earlier inline-name decode is also resolved: the wire body has
NO `RequireId` element at the bottom — the trailing `Inline("referenceTypeField")` was a dict-id wraparound or auto-intern artifact, not actual content.

design/followups.md F34 updated with the full ground-truth header,
plus a refined "Resolves when" pointing at the underlying
`nbfx.rs::decode_tokens` auto-intern semantics. The current codec's
doc comment ("the codec doesn't auto-intern") is correct for raw
[MC-NBFX] but wrong for WCF binary messages where the writer
auto-interns by convention; that's the structural fix the F34 binary
rewrite depends on.

No code-path change in this commit beyond the test improvements.
