fix(webui): sp1 review round, a switch carries nothing across and first run keeps its board (#1873, lane sp1)

- First run (no organization yet) keeps #/ as its board; the router no longer rewrites it to
  #/dashboard, which first run cannot draw.
- An organization switch stops the agents section's request poll and clears what it held. A
  route-change restart chain finishes on the organization it started in.
- A write in flight at a switch drops its answer: an org epoch in bus.js, checked after each
  await. The switch clears every busy flag, receipt and reply, and the doc drafts.
- The bus banner reads org state again only when the route crosses /dashboard, not on every
  hashchange inside one organization.
- The down banner does not repeat its heading as the reason.
- Tests: first run wordmark, poll stop on switch, restart pinned to its organization, settings
  save in flight at a switch, banner without a repeated reason. The org-switch test comment and
  wait match the in-place switch.
