docs(conflicts,queue): Beam WO5 batch — 13 endpoints backfilled, registry pinned

Beam added frontmatter + provenance + labeled examples to the 7 conflict and
6 queue docs, fixing real field drift on the way (resolve response keys,
bulk result shape, dismiss-all deleted count, queue stats counts).

Claude registry verification found TWO Beam catches of Claude's own draft:
- queue routes use :device_id / :item_id params (registry first draft said :id)
- resolve_conflict DOES take a body (ConflictResolutionRequest) — registry
  first draft said nil
Both fixed; gate then surfaced one real Beam defect: example-request used a
nonexistent "resolution" field in resolve + bulk-resolve (real contract:
winner=<source|manual> with required manual_data for manual; strategy=
most_recent|highest_progress|manual). Fixed in the docs.

Pinned by type: ConflictListResponse, ConflictDetailResponse,
ConflictResolveResponse, BulkResolveRequest/Response, QueueStatsResponse,
ConflictResolutionRequest. dismiss-all deleted is an int count.
