A Material 3 based extended Dark & Light theme for Home Assistant.

This theme not only defines Material 3 dark and light mode colors, but also adapts some of the Home Assistant colors in dark mode as advised by Material 3:

• The error, warning, success and info colors
• The energy dashboard colors
• The label badge (red, blue, green, yellow, grey) colors
• The state climate colors
• The state (on, off, home, not home, unknown, idle) colors

All these colors have been desaturated a bit and given more brightness to have a better match with the dark mode.

The theme also defines some Neumorphic shadow colors for dark and light mode.
