feat: refactor triggers

[damru]

🥇 Kudos to @JonMerlevede in #33 for this.

This pull request updates the ikea_simple-remotes_control-anything.yaml and ikea_simple-remotes_control-light.yaml blueprints to improve compatibility and flexibility with both MQTT and ZHA integrations. The main changes introduce conditional enabling of triggers based on which integration is available, and simplify action logic to reduce duplication and improve maintainability.

Conditional Trigger Enablement and Logic Simplification:

• Added trigger_variables to both blueprints, defining mqtt_enabled and zha_enabled flags to detect available integrations and conditionally enable triggers accordingly.
• Updated all relevant triggers in both blueprints to include an enabled field, which uses the new variables to ensure triggers are only active if the corresponding integration is available.

Action Logic Refactoring:

• Simplified action sequences by removing redundant choose blocks and using the new enabled flags on wait_for_trigger steps, making the automation logic cleaner and easier to follow.

These changes make the blueprints more robust and adaptable, ensuring they work seamlessly whether MQTT or ZHA integration is used.
