Use conditionals for app-button and remove the @apply inside css

[florinmtsc]

Temporarily the budget limit for the css is bigger than what it should be (not a huge deal but let's make it as optimized as possible) due to the use of @apply inside a couple of CSS files.

We need to use conditionals and use tailwindcss instead of using @apply inside CSS files.

After making sure no @apply is used inside CSS files, revert back to original the maximumError for production budget type "anyComponentStyle"
