“Search in files” for File Editor (search all YAML)

[slurpey]

Add a “Search in files” feature to File Editor that scans all .yaml/.yml under /config and lists every file and line where a given string appears, with clickable results that open the file at that line.

For example, if you rename a sensor from kitchen_temp to L1_kitchen_temp, you can quickly find every place in your YAML where kitchen_temp is still referenced and update it.
