Replace twind styles with inlined styles for the locator package

[thetarnav]

We decided to use twind for styling, because it supported Constructable Stylesheet Objects that can be used for styling ShadowDom elements.
Unfortunatelly they aren't fully supported in all of the browsers (#33) and we are moving away from twind in the rest of the packages as well.
So the locator styles should be rewritten to use <style></style> tag styling.

Using unocss here should be an easy swap.
