feat v1.38.2: restore last space and editor mode across reloads

- LS_NAV stores {space, mode}; restored in setConfig from the cached
  config, with a retry after the live config when the cache was stale;
  deep-link hash wins; edit modes restored for admins only
- UX-MODES updated (owner reversed the 'always start in View' rule)
- smoke_nav_persist.mjs; TESTING/CHANGELOG same-commit
