fix: important information now displays correctly on event details

Browse Source 
Fixed HTML parser to strip <style> and <script> blocks entirely
(including their content) before extracting text. Previously, CSS
rules like "td {border: 1px solid...}" leaked into the parsed output.
Also added </div>, </p>, </li> as newline separators so div-wrapped
content (common in Django admin rich text) parses into separate items.
Added debug logging to _loadFullDetails for troubleshooting.
