Fetch the map-schedule from arctrackers.io

[baschny]

Summary

This PR introduces automated synchronization of map event data from the arctracker.io API, eliminating the need for manual updates.

Changes

Automation Script (scripts/update-map-events.js)

• Fetches current rotation schedule and event localizations from https://arctracker.io/api/map-events
• Transforms API response into the repository's map-events.json structure
• Preserves local event type metadata (icons, descriptions) while updating schedules and translations
• Validates that all event types referenced in the schedule exist in the configuration

GitHub Actions Workflow (.github/workflows/update-map-events.yml)

• Manually triggered workflow to fetch latest map events
• Configurable branch names for automation and PR target
• Creates a pull request automatically if changes are detected
• Labeled with automation tag for easy filtering
• Skips PR creation if no changes occurred

Formatting Configuration

• Extended Prettier config to handle map-events.json structure
• Numeric sorting for hour keys in schedules (e.g., "0", "1", "2"...)
• Deterministic field ordering for eventTypes and schedule objects

Package Scripts

• bun run map-events:update – runs the update script and reformats the output
• bun run map-events:format – standalone formatter for map events file

New Event Types

• Added support for bird-city event type in the dataset

As soon as this is merged, in your Github project there will be a new "Action" which can be triggered manually:

So we can push this button from "time to time" at first. If this works out good, we could automate that further, making the workflow a scheduled workflow, maybe even also merging the pull request instead of just opening it.
