✨ feat(planta): add plant care tracking application

Add new Planta project for plant care management with:

Backend (NestJS):
- Plant CRUD with species, location, and care requirements
- Watering tracking and scheduling
- Photo management with S3 storage
- AI-powered plant analysis using Google Gemini Vision API
- Drizzle ORM with PostgreSQL schema

Web (SvelteKit):
- Dashboard with plant overview
- Plant detail pages with care history
- Add/edit plant forms
- Auth integration with login/register routes
- API client layer for all endpoints

Infrastructure:
- Database setup in setup-databases.sh
- MinIO bucket for plant photos
- Environment variables for port 3022
