* Small adjustments

About the report part.

* Update time format

* Fix embedded SVG fill attribute

SCSS darken/lighten functions may not return a color value, but a color
name like "white".  See following example:

https://www.sassmeister.com/gist/c41da93b87d536890ddf30a1f42e7816

This patch will normalize $color argument to FFFFFF style.

I also changed the function name from "url-friendly-colour" to
"hex-color", Because...

1. The name "url-friendly" is not meaningful enough to describe what it
   does.

2. It is familier to me using "color" rather than "colour"

(This patch has been merged as bugfix and reverted, but still valuable as
improvement)

Previously, we've attached IntersectionObserver twice for boosted statuses:
wrapper Status and wrapped Status. but wrapped Status don't need to manage
intersection and visibility by itself, because it's a part of wrapper Status.
