feat(ui): reorder engine/model/iterations fields — engine first across all 3 locations

[aaight]

Summary

• project-harness-form.tsx: Reordered fields from Engine → EngineSettings → Model+MaxIter (2-col) to Engine → Model → EngineSettings → MaxIterations (standalone)
• project-agent-configs.tsx: Reordered Engine tab from Model+MaxIter (2-col) → MaxConcurrency+Engine (2-col) → EngineSettings to Engine → Model → EngineSettings → MaxIter+MaxConcurrency (2-col)
• agent-config-form-dialog.tsx: Reordered from AgentType → Model+MaxIter (2-col) → MaxConcurrency → Engine → EngineSettings to AgentType → Engine → Model → EngineSettings → MaxIter+MaxConcurrency (2-col)
• project-agent-configs.tsx: Renamed table column header from 'Model / Engine' to 'Engine / Model' and swapped display order in AgentRow

Test plan

• Verify project Engine tab shows: Agent Engine → Model → (Engine Settings, if applicable) → Max Iterations
• Verify per-agent config Engine tab shows: Engine → Model → (Engine Settings, if applicable) → Max Iterations + Max Concurrency (2-col)
• Verify global agent config dialog shows: Agent Type → Engine → Model → (Engine Settings, if applicable) → Max Iterations + Max Concurrency (2-col)
• Verify agents list table header says 'Engine / Model' and rows show engine first
• Test engine-model interaction: selecting Claude Code/Codex shows dropdown for model, LLMist/OpenCode shows text input
• Verify engine settings appear/disappear correctly when engine is changed

LGTM — Pure UI reordering that consistently places Engine first across all three locations (project harness form, per-agent config tab, global agent config dialog). Field ordering is now uniform: Engine → Model → Engine Settings → remaining numeric fields. The table header and row display order in the agent list are updated to match. No logic, props, or state management changes — just JSX element repositioning. All CI checks pass.
