fix: correct city selection when multiple cities are available for a ZIP code

When multiple cities are available for a ZIP code, the bot now correctly selects
the city specified in the YAML file's location field instead of always choosing
the first option.

The change:
- Adds logic to select the correct city from dropdown based on location field
- Adds a small delay after ZIP code input to allow dropdown to populate
- Uses proper WebScrapingMixin method to read dropdown options
