Read Model Updates From Bot Management Simulator Events

[DakotaCondos]

As an admin user,
I want admin bot management actions to update the readable bot representation only through simulator-published events,
so that the simulator remains authoritative for bot state.

Acceptance Criteria

• Given an admin creates a bot
  When the simulator publishes BotCreated
  Then the read model creates the bot document.

• Given an admin updates a bot
  When the simulator publishes BotUpdated
  Then the read model updates only after the event.

• Given an admin removes a bot
  When the simulator publishes BotRemoved
  Then the read model marks it removed.

• Given the admin app performs management actions
  When those actions complete
  Then the admin app does not directly write to Cosmos DB bots.
