FN-7087: speed up SettingsModal remote tests

Optimize the SettingsModal remote-notifications shard by rendering target sections directly.

- Add a section-targeted SettingsModal test harness helper.
- Reuse the no-delay shared user event instance across remote-notifications tests.
- Update velocity baseline documentation and history with the faster shard timing.

 ## Measurement failures
 
-- None recorded.
+- Changed-only tests (`pnpm test`): exit 1 after 31.0s. The failure was outside the FN-7087 SettingsModal scoped run, so the weekly generated snapshot was hand-corrected with the successful split SettingsModal measurement pending the next fully green weekly refresh.
 
 ## Timing snapshot notes
 
-- No stale or missing timing metadata detected in the rendered slowest-file rows.
+- FN-7087 manually replaced the obsolete `SettingsModal` monolith entry with the four current split files measured by `pnpm --filter @fusion/dashboard exec vitest run --project dashboard-app-quality-settings --reporter=default --silent=passed-only`.
+- One historical slow-file entry in `scripts/test-timings.json` still points at a removed ChatView path; refresh `scripts/test-timings.json` after the changed-only lane is green before selecting the next slow-test rewrite from this report.
