fix(client): copies over plain HTTP, Vietnamese IME Enter, stale replies; react-router 7

- Every Copy goes through copyText: on http://<lan-ip> navigator.clipboard
  is undefined, so the push token (shown once), snapshot links, tool paths and
  hosts copied nothing, silently or with a TypeError.
- Inputs that submit on Enter use isSubmitEnter, so committing an IME
  composition (Vietnamese) no longer saves a half-typed pet name, jumps the
  settings search, or submits a cut-off plugin/MCP/marketplace spec.
- LaneChangesPanel, Workspace features/proof and AiToolConfig drop a reply
  that lands after the next request started: opening file B before file A's
  read returned showed (and let the editor save) A's text under B's header.
- Error-state Retry buttons spin through useSpin; ImageLightbox uses useDialog.
- react-router-dom 6.30 -> 7.18.4 (GHSA-wrjc-x8rr-h8h6, GHSA-337j-9hxr-rhxg);
  screen snapshots gain only Link's data-discover attribute.
- StatusBar test follows v2.8.17's "Settings → AI tools → Profiles" text.
