refactor: refactor miot mips & fix type errors

[chemwolf6922]

Why is this change made

The mips module uses tev as the event loop. Since asyncio is already widely used in this project, it would be better to change the event loop to asyncio to align the stack.

Changes

• Remove mips's dependency on tev
• Change IPC method to asyncio's call_soon_threadsafe
• Fix type errors
• Refactor some spaghetti code

Tests

• Tested with my local setup (cloud connection). Initialization and device state update works normally.
• Please help test in more complex scenarios.
