# What this PR does
- autogenerate new types exposed by backend, remove custom types that
duplicate autogenerated ones
- use autogenerated types for alert receive channels
- in alert_receive_channel model:
- use autogenerate http client (`onCallApi`) for http requests
- extract methods that don't update state into
alert_receive_channel.helpers.ts and make them pure (they accept
AlertReceiveChannelStore as param) to avoid inconsistency and issues
with `this` binding
- use `makeAutoObservable`
- remove unneeded decorators
- rename update* methods to fetch* whenever such methods retrieve data
from backend with GET requests
- in other models use `@action.bound` for actions and arrow functions
for store methods that are not actions (in subsequent PRs we will apply
the same changes as in alert_receive_channel, this is just for now until
we do it)
- refactor http-client so that it shows global notification on http
errors automatically and provide the possibility to opt-out from it when
making a call
- improve type-safety of `GSelect`
- fix bug related to attaching alert group
