Filter ResizeObserver loop errors from dev server overlay (#30125)

The @rspack/dev-server overlay catches ResizeObserver loop errors as
runtime crashes, showing a full-screen error overlay that blocks
development. These errors are benign — they originate from
lit-virtualizer (used by ha-data-table) and simply mean not all
resize observations could be delivered in a single animation frame.

Add a client.overlay.runtimeErrors filter to the dev server config
that suppresses ResizeObserver loop messages while still surfacing
all real runtime errors.
