feat(gui): port journey-level nav + local-first pill to the live app

Brings the live Streamlit app in line with the finalized layout-review
mockups (structural/low-risk changes; verified by compile + registry
sanity, still pending a streamlit-run visual check):

- tools_registry: Data Cleaners now in pipeline order (Clean Text ->
  Standardize -> Fix Missing -> Find Duplicates); new "finance" section
  (Reconcile, PDF to CSV) and "coming_soon" section (Find Unusual,
  Quality Check, Combine Files). Adds those to the Section type +
  SECTION_LABELS.
- app.py: Home becomes the "Start here" front door — a standalone,
  unlabeled top entry (play_circle icon) ahead of the hidden
  Activate/Logs/Close pages; nav groups reordered cleaners ->
  transformations -> automations -> finance -> coming soon.
- _legacy.py: render_tool_header now shows the "Runs 100% locally"
  privacy pill (right-aligned, Ready tools only — omitted on Coming
  Soon stubs); accent emphasis CSS for the Start-here nav link.
- i18n: add nav.start_here_title, nav.section_finance,
  nav.section_coming_soon to en + es packs.
- DECISIONS.md: log the PDF/Reconcile in-bundle (Finance group) call.
