feat(config): migrate configuration management to viper
Replace manual environment variable parsing with Viper to support file-based configuration. - Enable loading config from `config.yaml` or `./config/config.yaml` - Allow custom config path via `EZ_CONFIG_FILE` environment variable - Bind existing environment variables to maintain backward compatibility - Update documentation with configuration examples and precedence rules

|
||||
```yaml
|
||||
server:
|
||||
port: 8080
|
||||
postgres:
|
||||
dsn: host=localhost user=postgres password=postgres dbname=ezapi port=5432 sslmode=disable
|
