* 🐛 Stop browser logging from crashing on empty levels
Stop level->int crashes from taking down the dashboard when a
nil or unknown level reaches the browser logger. Invalid levels
now warn and are ignored in enabled?, setup! and the console
handler, which renders unknown records with a neutral fallback.
Alias the schema-legal :fatal level to :error in the browser
mappings and validate the JS-exported debug.set_logging, which
previously threw on missing arguments and wrote unreachable
keyword keys into the loggers map.

* 🐛 Guard logger args and strengthen logging tests
Close the residual throw paths next to the empty-level crash:
guard non-string loggers in enabled? and setup!, coerce
set_logging arguments safely, and validate logger keys.
Strengthen the regression tests so the fatal alias cannot
regress silently: enabled-logger filtering, JVM fatal and bogus
cases, setup! skip proof, and invalid-logger cases.

* 🐛 Address low findings from logging review
Validate the logger before the level in console-log-handler,
share a public valid-logger? predicate with debug/set-logging,
and keep warn formatting consistent across boundaries.
Document the fail-soft-FE/strict-BE split on enabled? and the
valid-level? contract on set-level!. Cover safe fallbacks, bad
logger keys, handler logger skips, and loggers-map isolation in
common tests, and add a frontend test for debug/set-logging.
