Modal (micro size) height should be dependent on the content inside

[xionatan]

The size (height) of the micro modal should be dependent on the content inside the modal, meaning that instead of .ts-modal.ts-micro {height: calc(100% - (20px * 5 * 2));} we should have .ts-modal.ts-micro {max-height: calc(100% - (20px * 5 * 2)); height: auto;} and set the default height to auto.

Also, no matter what the height is, the modal should be positioned screen center (vertically and horizontally).
