[fix] Droid: dynamic x-api-provider and custom User-Agent support

- Dynamic x-api-provider selection for OpenAI endpoint based on model
  - Models with '-max' suffix use 'openai' provider
  - Other models use 'azure_openai' provider
  - Fixes gpt-5.1-codex-max model compatibility issue

- Update default User-Agent to factory-cli/0.32.1

- Add custom User-Agent field for Droid accounts
  - Backend: userAgent field in createAccount and updateAccount
  - Frontend: User-Agent input in account creation/edit UI
  - Supports all Droid auth modes: OAuth, Manual, API Key

This resolves the issue where gpt-5.1-codex-max failed with 'Azure OpenAI only supports...' error due to incorrect provider header.
