infra: convert main.bicep to deployment router, remove old flat modules

Convert top-level infra/main.bicep and main_custom.bicep into thin deployment
routers (matching agentic-applications PR pattern) that dispatch to:
  - ./bicep/main.bicep (vanilla, deploymentFlavor='bicep')
  - ./avm/main.bicep   (AVM, deploymentFlavor='avm' or 'avm-waf')

Remove old flat infra/modules/ (6 camelCase files) — replaced by structured
subdirectories under infra/bicep/modules/ and infra/avm/modules/ with proper
ai/, compute/, data/, identity/, monitoring/, networking/ subfolders.

Update main.parameters.json to include deploymentFlavor param.
Update main.waf.parameters.json to set deploymentFlavor='avm-waf'.
Add SERVICE_* and CONTAINER_FRONTEND_* outputs to bicep/main_custom.bicep.
