Dogusata/fix stream animation flows and card orders

Problem

<span class='typewriter-part>...</span> shows up in contents within list items.
Chat card component reordering and update structure is broken sometimes depending on update type.

Streaming content component wrapped out from the chat-item-card and builded as a separate component
Typewriter animation injection removed from the markdown parsing process
Typewriter animation injection added to node process state with a check if the node type is TEXT, then we're adding the animation wrapper.
Converted some components to exportable ones.
Moved related scss file loads to their own or related components
Updated some component's code structures to match them repo wide
