deps: replace tracing with log+env_logger, drop console-subscriber

Switch all tracing::{info,warn,error} to log::{info,warn,error}.
Replace tracing_subscriber::fmt::init() with env_logger::init().
Drop tracing, tracing-subscriber, tracing-appender as direct deps.
Drop console feature from jobkit (was pulling in console-subscriber
which pulled in tracing-subscriber).

tracing still compiled as transitive dep of reqwest and tui-markdown,
but our code no longer depends on it.
