[filesapp] Append sourceURL to JavaScript foreground elements

Append sourceURL comment to allow Devtools to map parsed scripts back to
their source location. This new source location is surfaced in the
Sources tab in Devtools as well as the Chrome Devtools Protocol event
Debugger.scriptParsed which is used during JavaScript code coverage.

This also updates 2 of the vars to const's for the FilesToggleRipple and
the FilesRipple.
