Dark mode and minor interface tweaks

[DevonRD]

Does the following:

• Adds dark mode
  Overhauls the vuetify theme structure to allow for a seamless transition between light and dark themes. Also paves the way for an easy implementation of user-created custom themes in the future - when I get some more free time! This still has some minor cleanup on the way, but only for behind-the-scenes structure.
  Note: the light mode is not completely identical to the existing default theme. For the purpose of organization and consistency, I ended up changing some button colors/banner colors/etc to hopefully make things more intuitive. For example, button colors were sort of all over the place, so I tried to stick to red for deleting, yellow for more "active" actions (e.g. finish calibration, restart, change settings), and blue for more "passive" actions (e.g. open/close a popup, display a stream, show details). Open to suggestions about this. These minor changes will probably go unnoticed if you don't compare side by side.

• Replaces banners with alerts for better style control, a necessary change for theming

• Fixes calibration settings filtering for unrelated board type (switch to v-if instead of v-show, which wasn't working properly). Some input on this would be nice to make sure the existing filters are right for chessboard vs charuco.

• Adds a nicer-looking documentation page when running in dev mode because the old one made me want to vomit. Enjoy

• Fixes wrong delete message when deleting a camera from either camera matching or camera settings page
• Slightly increases button icon sizes for increased visibility
• Fixes spacing in camera matching view "more cameras here" card

I see a lot of lines have been compacted for no apparent reason, but honestly, I like it better that way, so I'm fine with leaving it. Also like the reordering of things like the pipeline actions and the items for each camera card in Camera Matching. I think it makes more sense that way.
