Modernize Execution Navigator execNavigator

Modernize-Execution-Navigator-execNavigator (#1562)

The standalone Execution Navigator — lib/execute/execNavigator.php (+ gui/templates/dashio/execute/execNavigator.tpl) — is modernized as a standalone Dashio screen backed by a REST BFF. It was the last standalone lib/execute/* screen without a modern twin; it renders the execution-status tree of a test plan (the old ExtJS "Execution Navigator" left frame) and deep-links into execTest.html, execDashboard.html, execExport.html and resultsImport.html.

Deliverables

• Screen: gui/templates/execute/execNavigator.html — Dashio page: tee-al header with tree context (build + opened-nodes links, one-click expand/collapse, reopening "Execution Navigator" / "Open test specification" html links), a filter panel (Result Passed/Failed/Blocked/Not run/No result + TC-ID prefix filter, Apply/Reset), and the legacy tree pipeline: suite/case nodes with exec-status counters (passed,failed,blocked,notrun) and [n] version brackets; leaf click opens execTest.html, root click opens execDashboard.html; Export execution report → execExport.html (tree / 4 results); Import results → resultsImport.html. Localized footer (footers.execNavigatorView), TLi18n locale switcher, access-denied / load-error states.
• BFF: api/execnavigator/index.php — GET ?action=init (session auth + bffSameOriginGuard), ports the legacy pipeline tlTestCaseFilterControl($db,'execution_mode') + execTree() with checkAccessToExec() rights (testplan_execute OR exec_ro_access on the owning project, admin shortcut) + loadExecDashboard EXDS load-down semantics. JSON contract: 401 (anon) / 403 (no exec rights on owning project, CSRF) / 400 (unknown action, tproject↔tplan mismatch, missing params) / 404 (unknown test plan) / 405 (non-GET). debug=1 returns the raw context for triage. Sends setting_testplan again on filter apply so the filters survive apply.
• Link switch: $actions->execNavigatorView in lib/functions/common.php (execute area, tplanID > 0); the footer link points at the modern screen.
• Shim: lib/execute/execNavigator.php kept as a session-guarded 302 redirect onto the modern screen (anon → login) so legacy deep links (ltx.php?load&item=exec...) still resolve.
• i18n: exnav.* (31 keys) + footers.execNavigatorView in all 10 bundles (en/ro/de/es/fr/it/ja/pt/ru/zh). Initial close-out pass found all 31 exnav.* values were untranslated English copies in every non-EN bundle and the footer key was missing everywhere — both were fixed (c38b836e9), validated with python3 -m json.tool; RO locale verified in-browser ("Navigator de execuție").

Verification

• Browser (admin): tree renders with counters + version brackets; filters (Passed / Not run / TC-ID ENAV1562-1 / Reset) narrow correctly; leaf → execTest.html?tcase_id=4&tcversion_id=5; root → execDashboard.html; export → execExport.html?…&exportContent=tree|4results; import → resultsImport.html; RO locale renders translated labels; console clean.
• BFF curl contract: 401 anon, 403 norights user, 404 tplan_id=999, 400 tproject↔tplan mismatch + bad action, 405 POST → 403 CSRF, debug=1 200.
• Event Viewer clean after the run (only pre-existing audit/login rows, 0 ERROR/WARNING).
• Fixture tmp/fixtures_1562.php re-runs clean on a fresh DB (project 1 "ExecNav Demo" / ENAV1562, plan 2, open + closed builds, Win11 platform).

Test cases

Suite 1562 (Screen — Execution Navigator) in tmp/TLU_Test_Cases.md — 12/12 PASS.

Bugs related

• #1567 — legacy SQL defect surfaced while building this screen: duplicate EB alias in getLinkedForExecTree() (lib/functions/requirement.inc.php) → MySQL error 1066. Fixed separately (8df9348b8), out of scope of the modern screen's parity.
