MoYeRanQianZhi 31934ae04c feat(codex): enable image generation for all Codex upstream requests ...

Codex CLI gates the built-in image_generation tool behind
AuthMode::Chatgpt (OAuth only). When clients connect via API key
auth through CPA, the tool is absent from requests, making image
generation unavailable through the reverse proxy.

Changes:

1. Inject image_generation tool (codex_executor.go):
   Add ensureImageGenerationTool() that appends
   {"type":"image_generation","output_format":"png"} to the tools
   array if not already present. Applied to all three execution
   paths: Execute, executeCompact, and ExecuteStream.

2. Route aliases for Codex CLI direct access (server.go):
   Add /backend-api/codex/responses routes that map to the same
   OpenAI Responses API handlers as /v1/responses. This allows
   Codex CLI to connect via chatgpt_base_url config while keeping
   AuthMode::Chatgpt, which enables the built-in image_generation
   tool on the client side.

3. Unit tests (codex_executor_imagegen_test.go):
   Cover no-tools, existing tools, already-present, empty array,
   and mixed built-in tool scenarios.
