web: full SmallDialog component, one flexible meowbalt component

- fully stylized small dialog: header, title, subtext, state without meowbalt
- moved meowbalt into his own adaptive component, no need to import/create new ones for each emotion
- better types for dialog related stuff
- type for meowbalt's emotions
- better padding in small dialog
