feat(logging-p0): replace console.* with logger and add error logging before ERP throws

Eliminate console.* remnants in bootstrap, session-manager, migrations, and app entry
so startup and login failures are captured in log files. Add log.error before all 14
throw sites in ERP services (auth, extractor, cleaner, browser manager) to ensure
critical automation failures are traceable. Introduce capturePageContext utility for
defensive Playwright page state capture during error logging.
