Wear OS Ui

[Nailik]

change ui to fit on very small wear os screens:

• bottom menu as "initial screen"
• no static title bar -> scroll
• check if there are wear ui guidlines in material 3

i can imagine, that there are just two buttons launching the app:

• one to open rhasspy settings (shall be used at best only after installation)
• second to start recording / rhasspy command
