refactor(codex): simplify custom template with minimal config

**Changes:**
- Remove all comments from custom template (align with Claude/Gemini)
- Remove base_url field from template (user fills in form instead)
- Simplify getCodexCustomTemplate() - no locale parameter needed
- Keep preset configurations unchanged with their baseUrl values

**Template now contains only:**
- model_provider, model, model_reasoning_effort
- disable_response_storage
- [model_providers.custom] section with minimal fields

**Benefits:**
- ✅ Cleaner, more focused template
- ✅ Consistent with other apps (no comments)
- ✅ Forces users to fill base_url via form field
- ✅ Reduced template size from 35+ lines to 12 lines

Net change: -74 lines (codexTemplates.ts)
