feat(auth): disallow free-tier Codex auth during selection process

- Introduced `disallowFreeAuthFromMetadata` and `isFreeCodexAuth` to enforce skipping free-tier credentials.
- Modified scheduler logic to honor `DisallowFreeAuthMetadataKey` during auth selection.
- Updated `ensureImageGenerationTool` to skip tool injection for free-tier Codex auth.
- Added context utility `WithDisallowFreeAuth` and integrated with image handlers.
- Augmented relevant tests to cover free-tier exclusion scenarios.
