add SearXNG safe-search script and improve OWUI search env vars

- New configure-searxng-safesearch.sh: set strict/moderate/none level,
  disable engines that can't enforce the chosen level (torrent sites,
  mojeek, baidu, yandex, nvidious/piped/peertube video frontends),
  updates &safesearch= in SEARXNG_QUERY_URL, and restarts searxng
- Add RAG_WEB_SEARCH_RESULT_COUNT=5 and RAG_WEB_SEARCH_CONCURRENT_REQUESTS=10
  to Open WebUI env in both setup scripts
- Add &safesearch=0 to SEARXNG_QUERY_URL so the script can find/replace it
- Sync ENABLE_TOOL_SERVERS=true into laptop_full_setup.sh (was missing)

+# configure-searxng-safesearch.sh
+# Set SearXNG safe-search level and disable engines that can't enforce it.
+#
+# Usage:
+#   ./configure-searxng-safesearch.sh strict    # block explicit content
+#   ./configure-searxng-safesearch.sh moderate  # filter but not strict
+#   ./configure-searxng-safesearch.sh none      # unfiltered (default)
+#
+# What it does:
+#   1. Updates ~/docker/ai-stack/searxng/settings.yml
+#   2. Disables engines that don't honour the chosen safe-search level
+#   3. Updates SEARXNG_QUERY_URL in docker-compose.yml to pass &safesearch=N
+#   4. Restarts the SearXNG container to apply changes
