Expose Bot Read Data Through APIs

[DakotaCondos]

As a customer app or admin app,
I want to read bot state and inventory through APIs backed by Cosmos DB,
so that applications do not need to query the simulator directly for normal bot information.

Acceptance Criteria

• Given an app requests all bots
  When the API receives the request
  Then it returns bot documents or summaries from the Cosmos DB Bots container.

• Given an app requests a specific bot
  When the API receives the bot ID
  Then it returns the matching bot document from Cosmos DB.

• Given an app requests available bots
  When the API queries Cosmos DB
  Then it returns bots marked as available and not removed or disabled.

• Given an app needs inventory information
  When it queries a bot through the API
  Then the response includes the bot’s current readable inventory values.

• Given an app requests normal read-only bot information
  When the request is processed
  Then the API does not call the simulator HTTP endpoints for that read operation.
