feat(CardAnalysisWidget): add configurable theme control to widget config window

[xenonnn4w]

Purpose / Description

Add a theme control option to the Card Analysis Widget config window,
allowing users to enable or disable dynamic theming for this widget
individually. When disabled, the widget uses Ankidroid theme
colors instead of wallpaper-based colors.

Fixes

• Widget colors don't match theme colors #18873

Don't add a section in Settings for widgets. Don't add a global setting for all the widgets. Add an option inside each widget configuration page to set the widget theme individually.

as per this discussion with @david-allison here, https://discord.com/channels/368267295601983490/1235296459621007471/1397911335802503190 , it felt the best option.
I tried this (like that of your suggestion) way before coming to this conclusion but i was not able to come up with an idea of placement of this setting in the config window, like see here

A gear icon somewhere, an equivalent of a list preference at the top or bottom, an appearance fab at the top of the add one,...

There are many better alternatives.

@BrayanDSO looks good?

[BrayanDSO]

change the big button icon to a Gear icon, since both of its suboptions are about confuring the widget. It probably can be further simplified, but that's good enough for now.

Use "single choice items" in the dialog, with the options being Dynamic and AnkiDroid.

Use just Widget theme as the dialog title, with no message, just the single choice selector.

Updated description video to reflect latest changes.

[BrayanDSO]

Put Add deck as the primary action (the big one in the bottom), and the theme as the secondary one (with a palette icon)

(pallete icon)

[xenonnn4w]

change the big button icon to a Gear icon

So the main button will be the gear button, clicking on it will lead to two more i.e add deck ("plus icon")(this will be at place of gear icon) and widget theme ("pallete icon")?

[BrayanDSO]

yes

I'd propose blocking this on the following, as it'll impact how theming occurs. Once it's in, we can likely simplify the code:
