Anthbot Map v2.4.9.1

• Fixes Home Assistant thread-safety error #61 in the Next mow timestamp sensor: its one-minute refresh now runs as an event-loop callback instead of calling async_write_ha_state() from an executor thread.
• Keeps the existing one-minute Next mow refresh behavior, so time-dependent schedule state continues to update without waiting for new mower data.
• Prevents Recorder warnings for the Voice Pack select exceeding Home Assistant's 16 KiB state-attribute limit by keeping its large live catalogue/store/install diagnostics out of Recorder history while leaving them available to the current-state UI.
• Adds regression coverage for both the event-loop-safe Next mow refresh and the Voice Pack Recorder exclusion.
