Part A: shared app_list_row partial — ONE row grammar on four surfaces (v0.126.0)

- templates/app_row.html: app_list_row/app_list_row_end (layout_start/_end idiom) — icon+name
  (+optional secondary) left, caller action block right; compact 44px row; logoURL→PNG→
  optional FallbackIcon→hidden onerror chain
- applied: Távoli mentés toggle list, Visszaállítás restore-to-verify + .fab lists, dashboard
  Telepített alkalmazások (state edge + data-href preserved); Alkalmazások collapsed headers
  ALIGNED (icon+name left, status dot moved right before chevron; expander untouched)
- funcmap: dict + appHref; OffboxAppRow/AppBackupRow gain Slug
- style.css: .app-row family; stack-card/stack-info/stack-logo/stack-name/stack-desc/
  stack-actions rules retired (dashboard rows now shared); .app-backup-row-header matched
  to the shared row height
- scripts/app_row_dedup_gate.py: row markup single-sourced (red-proven: pasted old
  storage-path-item block → exit 1); render tests per surface (app_row_test.go)
- NO behavior change: toggle/download/expander actions byte-identical
