Support Bot Creation, Update, and Removal in the Read Model

[DakotaCondos]

As an admin user,
I want bot management changes to appear in the readable bot network representation,
so that the admin app can show the current bot fleet accurately.

Acceptance Criteria

• Given a BotCreated event is received
  When the Function App processes the event
  Then a new bot document is created in the Cosmos DB Bots container.

• Given a BotUpdated event is received
  When the Function App processes the event
  Then the corresponding bot document is updated with the changed bot metadata or operating configuration.

• Given a BotRemoved event is received
  When the Function App processes the event
  Then the bot document is marked as removed, inactive, or unavailable.

• Given a removed bot is queried
  When the API reads the bot document
  Then the bot is clearly identified as removed or inactive.

• Given a bot management command is sent to the simulator
  When the simulator publishes the resulting bot event
  Then the readable representation is updated from that event instead of being directly modified by the admin app.
