feat(azure): add model metadata, model picker, rename to Azure AI Foundry

- Add static model metadata for 29 Azure models (from models.dev)
  with Roo-specific flags (reasoning, tools, verbosity) matching
  openAiNativeModels
- Add model picker dropdown to Azure provider settings for model
  capability detection (context window, max tokens, pricing)
- Rename provider label from 'Azure OpenAI' to 'Azure AI Foundry'
  across all 18 locales
- Make API key optional (supports Azure managed identity / Entra ID)
- Update default API version from 2024-08-01-preview to 2025-04-01-preview
- Fix maxOutputTokens validation (filter invalid values <= 0)
- Handler separates deployment name (API calls) from model ID
  (capability lookup) with azureDefaultModelInfo (gpt-4o) fallback
- Remove unhelpful 'Get Azure AI Foundry Access' button
- Prevent stale model IDs from other providers carrying over
- Suppress validation errors on fresh provider selection
