Add env-configurable GA/form/map; remove & artifacts; verify clone completeness

- Remove 4 stray '&' files (crawl artifact) that duplicated footer/about-us/contactus/root
- Replace hardcoded GA id, form email, map src with placeholders (GA_ID, FORM_EMAIL, GMAP_EMBED)
- Add entrypoint.sh: envsubst injects env vars into HTML at container startup
- Add .env.example + .dockerignore/.gitignore guarding .env secrets
- Google Map type A (free embed, no API key) configurable via GMAP_LAT/LNG
- Verify: all 39 pages, images (38/home), content blocks (296) match original; 0 missing assets

+# entrypoint.sh — inject environment variables into static HTML before serving.
+#
+# Reads env vars (EasyPanel env / .env) and replaces placeholders in all
+# HTML files under /usr/share/nginx/html using envsubst (nginx:alpine includes it).
+#
+# Supported variables:
+#   GA_ID        — Google Analytics / GTM measurement id (e.g. G-XXXX). Empty = disabled.
+#   FORM_EMAIL   — email recipient for FormSubmit contact/RFQ forms.
+#   GMAP_LAT/LNG — coords for the free (no-API-key) Google Map embed (type A).
+#   GMAP_ZOOM    — map zoom (default 16).
+#   GMAP_EMBED   — full embed URL, overrides lat/lng if set.
+#
+# Any value left empty falls back to sensible defaults (see .env.example).
