Fix: add einops dependency required by AdaptFormer custom code

Production overhaul: pre-trained AdaptFormer model + detection quality improvements

Revert to satellite change detection only - remove landslide, pothole, detection type menu

Pothole YOLO pipeline: single-image mode, modular detector, red box visualization

Use manager email API for notifications (multipart/form-data); SMTP fallback

Revert Resend; use SMTP only, custom email API to be integrated later

Use Resend HTTPS API for email (HF Spaces); SMTP fallback for local

Full codebase audit: fix critical perf bug, security, error handling, dead code

Fix: writable data dir for HF Spaces, pin bcrypt 4.0.1
