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.

+# Product & architecture decisions
+
+A running log of decisions that aren't obvious from the code and would
+otherwise be re-litigated. Newest first.
+
+## 2026-06-08 — PDF to CSV and Reconcile stay in the bundle, under a "Finance" group
+
+**Decision:** `10_pdf_extractor` (PDF to CSV) and `11_reconciler` (Reconcile
+Two Files) remain part of the DataTools suite. In the sidebar they are
+segregated into their own **Finance** section, distinct from the
+file-cleaning tools.
+
+**Context / why this needed deciding:**
+- Both tools sit outside the documented 9-script cleaning architecture
+  (TECHNICAL.md / USER-GUIDE.md stop at the orchestrator).
+- They occupy the "reconciliation / manual data-entry" territory the
+  product's honest-positioning note explicitly placed outside a
+  file-cleaning tool's scope.
+- A journey-level UX review flagged that every extra tool in the main
+  sidebar raises the "which tool do I need?" load for a non-technical
+  buyer, so tools serving a different job should live in a clearly
+  different place.
+
+**Resolution:** Keep them in-bundle (they're built, useful, and ship
+today) but group them under "Finance" so the cleaning flow stays
+uncluttered. Revisit only if a separate finance-focused product emerges.
+
+**Implications:**
+- `tools_registry.py`: Reconcile + PDF to CSV carry a `finance` section.
+- Sidebar order: Start here → Data Cleaners → Transformations →
+  Automations → Finance → Coming soon.
+- This is the source-of-truth realization of the `layout-review/`
+  mockups (see `layout-review/shell.js`).
