Merge ha-paper-slider into ha-slider

[thomasloven]

Proposed change

Merge ha-paper-slider (which modifies some styles of paper-slider) into ha-slider (which fixes a rounding problem with paper-slider).

I don't understand why there were two of them anyway.

This could be breaking for custom card developers

ha-paper-slider is already "broken" by lazy-loading more-info dialogs.
Of the two sliders ha-paper-slider looked better but was lazy-loaded since 0.115, and ha-slider behaved better and was not lazy-loaded.
The new ha-slider is (currently) immediately loaded and now has the good looks of ha-paper-slider.

What is loading ha-slider?

[thomasloven]

The more-info controls for light entities. Through ha-labeled-slider.

[bramkragten]

But the more info controls are(were) lazy loaded?

[thomasloven]

You're right. I assumed some were notalways (bad typo) loaded, and that's why it worked.
But I found it:

frontend/src/dialogs/more-info/ha-more-info-dialog.ts

Line 32 in d9f4271

import "../../state-summary/state-card-content";

frontend/src/state-summary/state-card-content.js

Line 9 in d9f4271

import "./state-card-input_number";

frontend/src/state-summary/state-card-input_number.js

Line 9 in d9f4271

import "../components/ha-slider";

... which probably should be lazy loaded too...

[bramkragten]

I wonder if we should replace the state-card-content with the Lovelace entity row
