fix(drafts): preserve the user-typed draft_path on reload of draft-only items

The flow / app / raw-app editors all dropped the saved `draft_path`
back to the URL's `u/{user}/draft_{uuid}` slot the moment the user
reloaded a draft-only edit page: the route sourced the Path widget's
initial path from `page.params.path` instead of the previously-saved
`draft_path`, and the first user edit then mirrored that URL path
back into the autosaved draft — silently overwriting the friendly
name in both the row and the editor.

- Flow route: after computing `effectiveFlow`, override `flowInitialPath`
  with `effectiveFlow.draft_path` when set.
- App route: pass `newPath={(app.value as any)?.draft_path ?? app.path}`
  through to `AppEditor`; AppEditorHeader's `newEditedPath` default now
  prefers a non-empty `newPath` over the random `<adj>_app` seed (the
  `newApp && !newPath` branch keeps the `/apps/add` friendly auto-name).
- Raw-app route: surface `savedRawAppDraft.draft_path` onto `backendApp`
  so the `extractRawApp` path seeds `newPath` with the friendly name.

Reload + a subsequent edit now leaves `draft_path` intact for all three
kinds; verified end-to-end via the `/drafts/get_draft/...` endpoint.
