Enhance event occurrence parsing with new location patterns and improved issue handling

This commit updates the LocationParsingConfiguration to include additional location patterns such as "Exhibit Hall *", "Mtg. Room *", and "Online". The EventOccurrenceParser has been enhanced to better handle parsing issues, including skipping comment and continuation lines, and cleaning up location text. New methods for analyzing location parsing failures and categorizing issues have been added to improve reporting. Additionally, the UI has been updated to support larger input sizes for event occurrence text, ensuring a smoother user experience during data import.
