Sidebar nav now groups tools under Data Review / Data Cleaners /
Transformations / Automations via st.navigation, replacing the flat
auto-discovered list. Tool display names switch to action-first
phrasing (Find Duplicates, Fix Missing Values, Find Unusual Values,
Standardize Formats, Clean Text, Quality Check, Map Columns, Combine
Files, Automated Workflows) in EN + ES packs and on each page's H1.
The Data Cleaners section follows the requested order: Missing
Values → Outliers → Text Cleaner → Format Standardizer → Deduplicator
→ Quality Check. (Text Cleaner kept inside cleaners since the request
didn't list it but the tool still ships.) Registry now carries a
section field; helpers added: tools_in_section(), section_label().

Until now every test ran against core or the CLI; the Streamlit GUI
was verified by hand. This commit adds tests/gui/ — 139 AppTest-
driven tests behind a 'gui' marker so the quick loop
(``pytest -m 'not gui'``) stays at 1777 tests / ~10s while
``pytest`` runs everything (1916 / ~14s).
Coverage:
- test_smoke.py (59): every page renders in EN and ES, expected
substring present, sidebar selector mounted.
- test_chrome.py (18): language selector flips session state and
re-renders; quit button + farewell strings localize; tool-card
names use the active language.
- test_gate.py (9): require_normalization_gate no-op / warning /
short-circuit / hash-mismatch invariants; warning + button
localized.
- test_workflows.py (14): happy path per Ready tool — stash
upload, render, find primary action, verify result lands in
session state.
- test_dedup_review.py (8): Accept All / Reject All / Clear
Decisions wire through to review_decisions; apply_review_decisions
semantics (keep-all, merge, column override).
- test_advanced_panels.py (15): config_panel widget defaults and
options (algorithm, threshold, survivor rule, merge, multiselects,
config save/load).
- test_errors.py (4): garbage / empty / single-column uploads don't
crash; duplicate-target mapping raises InputValidationError.
- test_findings_panel.py (12): driven via a small standalone harness
page so we test the component without faking a file_uploader. EN
+ ES strings, per-tool grouping, open-tool button label, untargeted
expander, severity summary.
Shared infrastructure in tests/gui/conftest.py:
- ``stash_upload`` / ``stash_upload_without_gate`` — populate
session_state to pre-pass or block the gate.
- ``with_language`` — set ``ui_lang`` before run().
- ``collected_text`` — flatten title/caption/markdown/etc. into
one string for substring assertions.
- Auto-marking: every test in tests/gui/ gets ``@pytest.mark.gui``
via ``pytest_collection_modifyitems``, so the marker isn't
per-test boilerplate.
