chore: resolve remaining unbound-method lint warnings (#12206)

* chore: resolve remaining unbound-method lint warnings

Apply targeted fixes per call pattern: arrow wrappers when passing a
method as a callback, arrow-function class fields when the method
doesn't depend on `this`, and `.bind()` when capturing for later
invocation.

Also replaces the rfc6902 hasOwnProperty re-export with a small wrapper
function so callers don't reference an unbound prototype method.

* chore: memoize history.goBack callbacks

Stable identity prevents Button re-renders and avoids re-subscribing
the global keydown handler in RegisterKeyDown when the parent renders.
