This commit updates variable declarations from 'var' to 'let' in 'install.js' for better scope control. It additionally includes error-handling for undefined 'select_id' in 'parseAnsibleJsonOutput' function. The 'waf.js' file is moved to the 'app/static/js' directory and paths are updated accordingly in both 'waf.js' and 'waf.html'. The success handler in 'waf.js' is also updated to use 'parseAnsibleJsonOutput'.
