Update install process and add configuration file management

- Added mkdir command to create /etc/remindme_caldav directory.
- Copied config.toml to the new directory.
- Updated Makefile install instructions to include these changes.
- Updated comment in config.toml to provide a link to the readme for an example configuration.
- Removed placeholder values from all sections of the config file.
- Added check to ensure there are .ics files in the destination location before parsing them.
- If no files are found, log a message and exit with an error code.
