feat(v3-batch3): B3-WP4 — {{equip}}/<RefName> reference-relative resolution

Replace the deleted equipment-base-prefix {{equip}} mechanism (impossible now
that equipment is reference-only) with per-reference resolution:
{{equip}}/<RefName> resolves through the owning equipment's UnsTagReference rows
(by effective name) to the backing raw tag's RawPath. Every unresolved <RefName>
is a clear deploy error + authoring rejection + Monaco diagnostic — preserving
"editor accepts <=> publish accepts".

Commons:
- EquipmentScriptPaths: delete DeriveEquipmentBase; SubstituteEquipmentToken now
  takes the equipment's reference map (effectiveName -> RawPath) and substitutes
  {{equip}}/<RefName> inside path literals (unresolved left intact, never throws);
  add ExtractEquipReferenceNames (path-literal scoped) +
  ExtractEquipReferenceNamesFromText (message templates). Slash syntax replaces
  the v2 dot joint.
- New EquipmentReferenceMap: shared, input-shape-agnostic builder (entity + JSON
  sides) over RawPathResolver — the single authority both compose seams + the
  validator use, so resolved RawPaths agree byte-for-byte.

Compose seams (byte-parity kept):
- AddressSpaceComposer.Compose + DeploymentArtifact.ParseComposition both build
  the per-equipment reference map from UnsTagReferences + Tags + raw topology and
  substitute VirtualTag AND ScriptedAlarm-predicate sources before dependency
  extraction (runtime dep refs = resolved RawPaths).

Deploy gate + authoring + editor:
- DraftValidator.ValidateEquipReferenceResolution: EquipReferenceUnresolved error
  for unresolved {{equip}}/<RefName> in VirtualTag/ScriptedAlarm scripts + alarm
  message-template tokens (naming script, equipment, missing ref).
- UnsTreeService.ValidateEquipTokenAsync (Wave-A M1): reference-relative authoring
  rejection, replacing the stale DeriveEquipmentBase(empty)->reject-all logic.
- ScriptAnalysisService: {{equip}}/ completion offers the equipment's reference
  effective names; DiagnoseAsync flags unresolved refs (OTSCRIPT_EQUIPREF) same as
  the deploy gate. Requests carry optional EquipmentId (threaded MonacoEditor ->
  monaco-init.js -> fetch bodies). IScriptTagCatalog.GetEquipmentRelativeLeavesAsync
  repurposed to GetEquipmentReferenceNamesAsync(equipmentId, filter).

Tests: EquipmentScriptPaths substitution/extraction (slash pinned); composer<->
artifact reference-resolution byte-parity; DraftValidator unresolved-ref;
ScriptAnalysis completion+diagnostic; M1 authoring gate. Build clean (0/0); all
five affected suites green.
