fix(agents): Add error boundary around ModelsTable (#110509)

Wrap `ModelsTable` with `<ErrorBoundary mini>` on the agent models
landing page so that rendering errors (e.g. null `modelId` hitting
`.toLowerCase()`) are contained within the table instead of crashing the
entire page.

This follows the existing pattern of wrapping table consumers at the
call site. The widget footer error boundary was added in #110506 but
`ModelsTable` (a standalone `GridEditable` table) was unprotected.
