We now send "realm_user/update" (and "realm_bot/update" for bots)
events with "is_active" field when deactivating and reactivating
users, including bots.
We would want to use "remove" event for a user losing access
to another user for #10970, so it is better to use "update"
event for deactivation as we only update "is_active" field
in the user objects and the clients still have the data for
deactivated users.
Previously, we used to send "add" event for reactivation along
with complete user objects, but clients should have the data
for deactivated users as well, so an "update" event is enough
like we do when deactivating users.
Add type annotations. Create custom types for Bot and Service.
Add zod data validation for incoming bot data from server.
Based on `zerver/openapi/zulip.yaml` description, `add` operation
(`op`) carries data that follows `Bot` structure. So taking
reference from `bot` structure, I create `ServerAddBotData` zod
schema and infer its type. Similarly, `update` operation carries
data that follows `BasicBot`, so I create `ServerUpdateBotData`.
Note that `Bot` inherits from `BasicBot`.
`zerver/openapi/zulip.yaml` describes that `services` in `BasicBot`
can be one of two objects, one with `{base_url, token, interface}`,
another with `{service_name, config_data}`. Therefore, I create
two corresponding schema and infer their types.
Fix two test cases `bot_data.test.js` and `settings_bots.test.js`
whose synthetic objects should have had followed the schema.
