Resolves #3146.

StreamingReporter is prepended to ActionController::Live, but its log_error override was public. That changes the public method set of controllers including ActionController::Live and exposes log_error as an action.

This marks the override private and adds a regression spec that prepends it over a private log_error, then checks the resulting controller method remains private.

Checks performed:

• Ruby syntax checks for both changed files: passed.
• Focused RSpec example in an isolated Ruby 3.4 harness with a minimal spec_helper stub: 1 example, 0 failures.
• Direct Ruby prepend visibility probe: passed.
• git diff --check: passed.
