feat(graph): make the visual editor a full wiring control surface

Lets users wire the system end-to-end from the graph, and fixes the core
bug that made drag-to-wire silently fail.

- Fix drag-to-wire 422s across 5 entity kinds: updateConnection() now echoes
  the target's discriminator (source_type/stream_type/target_type) into the
  partial PUT, so value/colour-strip/audio/picture sources and output targets
  all wire correctly. New contract test (54 cases) in test_graph_wiring_contract.py.
- Re-wire composite layers / mapped zones from the graph (right-click a
  layer/zone source edge -> Re-wire). Whole-list write preserves every sibling
  layer/zone setting, with an optimistic-concurrency guard and undo.
- Secret-safe /graph topology: project entities to id/name/subtype + reference
  roots so the endpoint cannot leak webhook tokens or other credentials.
- Carry slot indices on list edges; node custom-icon + schema-drift refinements;
  rewire i18n keys (en/ru/zh); wiring-control roadmap (TODO.md).

"""Contract tests for graph drag-to-wire writes.
The graph editor's ``updateConnection()`` performs a *partial* PUT for a single
dragged edge: it sends only the reference (or bindable) field being wired. Five
entity kinds have ``Body(discriminator=...)`` PUT routes, so such a partial body
is rejected with a 422 unless it also echoes the entity's subtype
(``source_type`` / ``stream_type`` / ``target_type``). ``updateConnection()`` now
reads the target's subtype back and includes it.
These tests lock in that contract from the backend side: each ``(kind, field)``
pair the frontend ``CONNECTION_MAP`` drag-edits must validate as a minimal
``{discriminator, field}`` body — and must be rejected without the discriminator
(the exact failure that silently broke wiring). If a future schema change makes
one of these fields required-with-siblings, or drops a subtype, these tests fail
and flag that graph wiring will break.
