[AVC] Refactor commands and add new audit commands

[tjprescott]

This PR refactors the APIView Copilot CLI command surface (renaming/re-grouping several command groups) and adds new audit/reporting commands for examining AI comment feedback and stored memories in the AVC Cosmos DB, while simplifying environment configuration by deriving the App Configuration endpoint from ENVIRONMENT_NAME.

• Refactor CLI groups/commands (e.g., eval → test, search → kb, metrics → report, app/permissions → ops) and update docs accordingly.
• Add new reporting/audit commands (avc report feedback / avc report memory) and related support logic (including feedback language handling).
• Update settings/db/search managers to support environment-aware configuration and instance scoping.
