Move title.md default location to configs folder

As blurbs.md is located in configs folder, perhaps the default location of the title.md should follow the same?

Currently, the title.md file does not need any processing by the backend before being transmitted to the frontend, hence it was placed in the assets folder. However, with the introduction of the one-stop config file in #2161, it may be beneficial to include the title in the generated summary.json and move title.md to the configs folder.

Currently, the title.md file does not need any processing by the backend before being transmitted to the frontend, hence it was placed in the assets folder. However, with the introduction of the one-stop config file in #2172, it may be beneficial to include the title in the generated summary.json and move title.md to the configs folder.

Also, the file location should make sense from the user point of view. For them, the configs folder is where they put their 'customizations'.
