Add PDF reports, file uploads, admin auth, and comprehensive tests

Features:
- PDF service for generating task reports with ReportLab-style formatting
- Storage service for file uploads (local and S3-compatible)
- Admin authentication middleware with JWT support
- Admin user model and repository

Infrastructure:
- Updated Docker configuration for admin panel builds
- Email service enhancements for task notifications
- Updated router with admin and file upload routes
- Environment configuration updates

Tests:
- Unit tests for handlers (auth, residence, task)
- Unit tests for models (user, residence, task)
- Unit tests for repositories (user, residence, task)
- Unit tests for services (residence, task)
- Integration test setup
- Test utilities for mocking database and services

Database:
- Admin user seed data
- Updated test data seeds
