Rename module to DRE-Visualizations

Rename module to Rename module and repo to DRE-Visualizations and publish it in https://github.com/AM-Digital-Research-Environment

Mostly done in v2.0.0 (commit 641ca29, on main):

• ✅ Module renamed ResourceVisualizations → DreVisualizations (display "DRE Visualizations"): PHP namespace, assetUrl() paths, admin route (/admin/dre-visualizations), CSS file, view dir, tests and docs. The deployed module folder must be DreVisualizations.
• ✅ Repo transferred to AM-Digital-Research-Environment.
• ⬜ Repo rename ResourceVisualizations → DRE-Visualizations — needs an org owner. I couldn't do it via API (I have push/triage but admin:false on the repo). An owner can do it in Settings → General → Repository name, or grant admin and I'll finish it. (module.ini module_link + the README/omeka-s-cli refs already point to DRE-Visualizations, so that URL resolves once renamed.)

Leaving this open until the repo rename lands.

⚠️ Deploy note: the namespace change makes this effectively a new module to Omeka. Replace the old ResourceVisualizations folder with DreVisualizations, reactivate, re-check the page blocks, and run "Regenerate now".
