Subject: [PATCH] Enable the ESLint `no-var` rule in the `src/display/` folder

Previously this rule has been enabled in the `web/` folder, and in select files in the `src/` sub-folders.
Note that a number of the files in the `src/display/` folder were already enforcing the `no-var` rule, and thanks to Prettier the necessary re-writing will be (mostly) handled automatically.

Please find additional details about the ESLint rule at https://eslint.org/docs/rules/no-var
