Rate-limited iframe refreshes: Stutter-Free Map Tracking

Summary

Version 1.8.0 adds a configurable update interval to prevent constant iframe reloads. If you use a high-frequency location tracker (like a USB GPS), this release eliminates looping map-reload animations.

Key Changes

• Configurable Update Interval [#23]: Adds an update_interval parameter (in seconds) to rate-limit updates to map and forecast iframes.
• Intelligent Throttling: Implements a combined leading and trailing-edge throttle, ensuring map reloads happen at most once per configured interval.
• Lovelace Editor Bypass: Configuration edits made in the dashboard editor apply instantly without waiting for the throttle.
• Translations: Updated Dutch, German, French, Italian, Spanish, and English localizations.
