Mac2MQTT v0.4.6

• A brighter, more even look: badges and states in bright colors of one
  lightness, flat badges, a quieter sidebar, page titles level with the
  app's name, and This Mac in three columns.
• Overview's status and Now Playing are Liquid Glass over soft light, and
  pages fade out under their title as they scroll.
• Entities opens on a summary: how many entities Home Assistant has from
  this Mac, and how many groups are on and off.
• Settings save as you change them, as macOS's do: a field saves when you
  leave it, and there is no Save button to press.
• When an update is available, the menu bar's menu, Settings and About say
  which version, with a button to update to it.
• The app icon's body has a faint depth.
