Dark Mode / Theming Consistency

[brian]

Dark mode support has been added. It follows your browser's setting. The support has been added across the site. With the implementation, more of the site aligns with a consistent theme. Most of the changes are in Links on mobile and the menus and buttons for the Forum and Gallery.

Weather location code has been rewritten.  I am using lookup-only APIs and wrote a very compact UI. Overall, the code size for the previous Google Maps API is over 300 KB. My code is less than 15 KB. Smaller, faster, and easier to change. Session-based local caching and rate limiting on the queries are built-in for efficiency and performance. If you had previously set your location, no need to update it.

Air Quality Index has been added to the weather display, providing more information to help you plan your day.
