fix(build): keep the server logger out of client bundles

The production webpack build failed with UnhandledSchemeError: client
components imported @/lib/logger, which binds pino, AsyncLocalStorage
(node:async_hooks), node:crypto and node:fs — and validates server env on
import. The UI fixture aliased those modules, so the harness and tests
never hit it.

- add src/lib/browser-log.ts: browser-safe logger with the same interface;
  errors are forwarded to /api/diagnostics/errors via reportBrowserError
- guard src/lib/logger.ts with server-only and drop its now-dead browser
  branches
- switch the 11 client components/hooks to @/lib/browser-log

Verified with the Dockerfile's production build (pnpm run build) and the
full vitest suite.
