v1.68.6 — clearer bilingual explanations for researchers

This release improves English and French explanations across all 21 visualization blocks and the resource-page dashboards, with language accessible to social scientists.

• Add missing chart captions and replace technical headings with clearer descriptions of the evidence shown.
• Explain catalogue tags, collection coverage, publication dates, modelled themes, vocabulary measures and similarity scores.
• Correct the newspaper-only scope of the radicalism vocabulary views and clarify that the Laïcité dossier searches titles and descriptive fields as well as full text.
• Present AI ratings, network associations and possible reprints as findings to investigate through the sources, with their limits stated explicitly.
• Update block descriptions, French translations, Laïcité frame notes and compiled assets. Revised frame notes also apply to older data bundles.

Validation: 182 JavaScript tests and 53 Chromium browser tests passed. Translation checks and the release-version checks passed; assets were rebuilt.

The module version is 1.68.6, which refreshes cached JavaScript and CSS on upgrade. No data refresh is required for the revised interface copy.
