- BackButton gains showLabel prop: showLabel=false renders icon-only with
aria-label, no mr-2 on svg (was causing 0px button width in topbar)
- DocumentTopBar: BackButton restored to h-11 w-11 circular touch target
with showLabel=false matching the original 44×44px <a> it replaced
- Topbar row gets pr-4 (16px right padding per spec); action buttons div
no longer needs its own pr-3

- BackButton now accepts a `class` prop (default 'mb-4') so callers can
override spacing; resolves hardcoded margin in flex-row topbar snippets
- documents/[id]/edit and enrich/[id] pass class="" to suppress the margin
- Replace weak className unit test with class-prop behaviour tests
- Add [data-hydrated] comment in E2E spec explaining what emits the attribute
