fix(oracle-r4): curation contradiction + wizard view enrichment

Oracle round-7 remediation, items 2 + 7:

- flowCuration.NON_BUSINESS_SOURCE_CONTEXTS no longer lists
  EA2_DRAFT_PROCESS:process_creation (it's in STARTABLE_SOURCE_CONTEXTS).
  Adds CANVAS_AGENT_MEMORY + CANVAS_AGENT_VAULT_ROOT to NON_BUSINESS so
  vault docs never leak into hubs / catalogue.
- wizardApi.createView now accepts a fields list and emits proper field
  defs (name slug, label, type from {string,number,boolean,textarea}).
- Wizard.handleDataSave rebuilds every step's view with the user's
  draft.fields after Generate phase, then rewires the presentation
  edges to the new views. Steps now expose real business fields, not a
  generic 'Notes' textarea.
