Alphaeus Mote bf70fba516 Fix Docker Compose version warning and improve script permissions
DOCKER COMPOSE:
- Removed obsolete 'version' attribute from docker-compose.yml
- Keeps db-ui image as ghcr.io/n7olkachev/db-ui:latest

SCRIPT PERMISSIONS:
- Updated README.md with recursive chmod command: find . -name '*.sh' -exec chmod +x {} \;
- Updated QUICKSTART.md with Step 0: Make Scripts Executable
- Removed individual chmod commands from each step
- Single command makes all .sh files executable at once

DOCUMENTATION:
- Renumbered steps in QUICKSTART.md for clarity
- Step 0: Make Scripts Executable
- Step 1: Install Dependencies (Optional)
- Step 2: Start Docker Containers
- Step 3: Initialize Database Schema
- Step 4: Generate Test Data

This resolves the Docker Compose warning and simplifies the setup process with a single chmod command.

Alphaeus Mote 3dde2997f6 Add automatic dependency installer and package checks
DEPENDENCY MANAGEMENT:
- Created scripts/install-dependencies.sh - automatic installer for all required packages
- Detects OS (Ubuntu, Debian, CentOS, RHEL, Fedora, Arch, macOS)
- Installs PostgreSQL client (psql) automatically
- Installs Docker & Docker Compose if missing
- Installs utility packages (curl, wget, git)

SCRIPT ENHANCEMENTS:
- Updated setup-database.sh with dependency checking
- Updated generate_data.sh with dependency checking
- Updated verify-setup.sh with dependency checking
- All scripts now prompt to run installer if dependencies are missing
- Interactive prompts guide users through installation

DOCUMENTATION:
- Updated README.md with dependency installation instructions
- Updated QUICKSTART.md with Step 0: Install Dependencies
- Added supported OS list
- Added automatic dependency check notes

USER EXPERIENCE:
- No more manual package installation required
- Scripts fail gracefully with helpful error messages
- One-command installation: ./scripts/install-dependencies.sh
- Automatic detection and installation on Linux/macOS
- Clear instructions for Windows users

This ensures users can get started immediately without hunting for package installation commands.
