[FIX] website_event_track: remove unused locations in agenda

This commit adapts the agenda template to avoid displaying a complete column
for a location if that location is unused for this specific day.

This allows having multiple different locations for your different event days
without cluttering the display by showing empty columns for unused locations.

Task-2942630

closes odoo/odoo#97537
