fix(mcp): apply_patch preserves schema-defaulted ids in multi-op batches

SceneBridge.applyPatch now threads the Zod-parsed node through to the
apply phase instead of the raw input. Previously, when a caller sent a
create patch without an `id` field, the schema's objectId default ran
during dry-run parsing but only in `res.data`; the apply phase pushed
the unparsed `p.node` (no id) to the store, so subsequent tools that
walked `level.children` crashed on undefined entries (e.g.
duplicate_level -> cloneLevelSubtree -> extractIdPrefix(undefined)).

Also adds test-reports/ artefacts from live end-to-end testing:
- t1-stdio: 21/21 tools pass via stdio (~106ms)
- t2-http: connect/single-session behaviour (HTTP transport quirk
  documented)
- t3-scenario: 2-bedroom apartment built end-to-end — 12/12 steps
  after this fix (24 final nodes, validate=true, apartment.json
  exported)
- t4-errors: 24/24 invalid-input cases rejected with proper MCP errors
- t5-resources-prompts: 4/4 resources, 3/3 prompts, dev server
  /api/health 200 OK
