Fix UV configuration and add Makefile

**Issues Fixed:**
- Removed [tool.uv.scripts] (not supported by UV)
- Updated requires-python from >=3.7 to >=3.8 (Flask requirement)
- Removed tool.uv.dev-dependencies (deprecated)

**Makefile Added:**
- make start - Run the wedding phone system
- make test - Run audio tests
- make install - Install dependencies
- make clean - Clean temporary files
- make help - Show available commands

**Service Updated:**
- Changed ExecStart from 'uv run start' to 'make start'
- Uses Makefile for proper UV execution

**Documentation Updated:**
- Primary method now uses Make commands
- Added UV direct commands as alternative
- Updated file structure to include Makefile

**Usage:**
```bash
# Recommended
make start

# Alternative
uv run python rotary_phone_web.py

# Service uses make internally
sudo systemctl start wedding-phone
```
