Enhancement(byte): On leave events

[JacobCoffee]

Summary

On Byte's removal or leave from a guild, we need to track this.

Basic Example

• add an active column to the Guild model -

  byte/src/server/domain/db/models.py

  Line 14 in 2ff7c4a

  class Guild(UUIDAuditBase):

Drawbacks and Impact

No response

Unresolved questions

• We should probably continue to store all data, so that if Byte is invited back we can offer "Restore previous config? or start fresh?" options.
