Sort swipe navigation events chronologically by start time

[Copilot]

Swiping left/right through the floating event card navigated events in arbitrary (data source) order rather than chronological order.

Changes

• map.js — Sort visibleEventsList by parsed start datetime when it's (re)built on each filter update, so left = earlier, right = later
• Uses a Schwartzian transform (map → sort → map) to parse each event's start timestamp once rather than on every comparator call
• Events with missing/unparseable date_text or time sort to the end (Infinity) instead of producing NaN-driven random ordering

// Before
visibleEventsList = window.events.get()?.filter(e => e.visible && e.title && e.geometry) || [];

// After
const getEventStartTime = event => {
  if (!event.date_text || !event.time) return Infinity;
  const timestamp = new Date(`${event.date_text} ${event.time.split(' to ')[0]}`).getTime();
  return isNaN(timestamp) ? Infinity : timestamp;
};
visibleEventsList = (window.events.get()?.filter(e => e.visible && e.title && e.geometry) || [])
  .map(event => ({ event, startTime: getEventStartTime(event) }))
  .sort((a, b) => a.startTime - b.startTime)
  .map(({ event }) => event);

Screenshot

Original prompt

swiping left and right. should move through events based on start time with earlier times being to the left and later start times being to the right. At this moment it looks like the swipe gesture order of events is random
