# Task 4+7: Fix SMTP .env Comments + Add Back Buttons Everywhere

## Agent: back-button-smtp-agent

## Summary

### Task 1: SMTP Configuration (.env)
- Updated .env with comprehensive SMTP instructions
- Added "CURRENT STATUS" header, step-by-step "HOW TO ENABLE EMAIL SENDING" guide, and "IMPORTANT NOTES" section
- No code changes needed to email.ts or forgot-password routes

### Task 2: Back Buttons
Added ArrowLeft back buttons to 13 dialog/detail views across 8 module files:
1. MarketplaceModule.tsx - product detail dialog (floating overlay on image)
2. MedicineModule.tsx - pharmacy detail dialog + health tip detail dialog
3. HouseRentalModule.tsx - house detail dialog (floating overlay on image)
4. ShopRentalModule.tsx - shop detail dialog
5. ProfileModule.tsx - edit profile dialog + change password dialog
6. OwnerDashboardModule.tsx - house form + shop form + upload choice dialogs
7. SellerDashboardModule.tsx - product form dialog
8. SettingsModule.tsx - change password dialog
9. CommunityModule.tsx - create post dialog

Verified all 16+ modules already have appropriate back buttons on their main views.
