fix: disable Sentry webpack wrapper in dev mode

The withSentryConfig() wrapper caused recurring worker.js crashes
in Next.js dev mode (vendor-chunks/lib/worker.js MODULE_NOT_FOUND).
This crashed the server mid-request during image generation and
other long-running operations.

Fix: only apply withSentryConfig in production. In dev mode, use
the raw Next.js config. Sentry instrumentation also gated to
production only.
