Auto-replace entity names across all configurations when renamed

[ShayLevy]

I'd like to propose a feature that would make managing Home Assistant configurations much smoother:

The Problem

When I rename an entity in Home Assistant (e.g., changing sensor.living_room_temperature to sensor.living_room_temp), all my existing configurations break or become inconsistent. I need to manually search and replace the old entity name across:

• Automations (YAML and UI)
• Dashboard cards
• Scripts
• Scenes
• Templates
• Any other Spook configurations

This is error-prone and time-consuming, especially in larger setups.

The Proposed Solution

Spook could detect when an entity name changes and automatically replace the old entity name with the new one across all configurations where it's referenced. This would include:

Detection: Monitor for entity renames (via Home Assistant's entity registry events)

Search & Replace: Automatically update references in:

• Automations
• Dashboard cards and configurations
• Scripts
• Scenes
• Spook's own ghost configurations
• Any YAML configurations managed by Spook

Safety: Optionally create backups before making changes, or provide a preview mode

Why This Would Be Awesome

Saves time: No more tedious manual find-and-replace
Prevents broken configs: Eliminates human error when updating references
Makes experimentation easier: I can rename entities without fearing I'll break things

Fits Spook's mission: Another powerful tool for Home Assistant configuration management

Thanks for building such an awesome toolbox! 🏡👻
