Replace custom logging with tracing crate and RUST_LOG env var

- Remove custom logging module and init_logging function
- Update main.rs to use tracing_subscriber with EnvFilter
- Remove log_level from global config structure
- Update documentation and tests to use RUST_LOG
- Format long lines in config.rs and test files for better readability

 ## Options
 
 - `--config` (`-C`): Path to config file (default `/etc/pollux/config.toml`)
-- `--no-tls`: Disable TLS for testing (uses raw TCP connections)
 - `--test-processing-delay` (debug builds only): Add delay before processing requests (seconds) - for testing rate limiting

 - `port`: Listen port (1965 is standard, per host override possible)
 - `max_concurrent_requests`: Connection limit (global)
