feat(providers): normalize image paths to data URIs in OpenAI Codex
Fix OpenAI Codex vision support by converting file paths to data URIs
before sending requests to the API.

## Problem

OpenAI Codex API was rejecting vision requests with 400 error:
"Invalid 'input[0].content[1].image_url'. Expected a valid URL,
but got a value with an invalid format."

Root cause: provider was sending raw file paths (e.g. `/tmp/test.png`)
instead of data URIs (e.g. `data:image/png;base64,...`).

## Solution

Add image normalization in both `chat_with_system` and `chat_with_history`:
- Call `multimodal::prepare_messages_for_provider()` before building request
- Converts file paths to base64 data URIs
- Validates image size and MIME type
- Works with both local files and remote URLs

## Changes

- `src/providers/openai_codex.rs`:
  - Normalize images in `chat_with_system()`
  - Normalize images in `chat_with_history()`
  - Simplify `ResponsesInputContent.image_url` from nested object to String
  - Fix unit test assertion for flat image_url structure

- `tests/openai_codex_vision_e2e.rs`:
  - Add E2E test for second profile vision support
  - Validates capabilities, request success, and response content

## Verification

 Unit tests pass: `cargo test --lib openai_codex`
 E2E test passes: `cargo test openai_codex_second_vision -- --ignored`
 Second profile accepts vision requests (200 OK)
 Returns correct image descriptions

## Impact

- Enables vision support for all OpenAI Codex profiles
- Second profile works without rate limits
- Fallback chain: default → second → gemini
- No breaking changes to existing non-vision flows

//! E2E test for vision support in providers.
//!
//! This test validates that:
//! 1. Provider reports vision capability
//! 2. Provider correctly processes messages with [IMAGE:...] markers
//! 3. Request is sent to API with proper image_url format
//!
//! Requires:
//! - Live provider OAuth credentials (OpenAI Codex or Gemini)
//! - Test image at /tmp/test_vision.png
//!
//! Run manually: `cargo test provider_vision -- --ignored --nocapture`
