[Dashboard] Surface inlineParallelCapable as an endpoint capability badge

[AndresL230]

Follow-up from Wave 3 / PR #126 (#116). The new inlineParallelCapable fingerprint flag is not exposed in the UI layer.

• dashboard/src/lib/types.ts + webview/src/types.ts EndpointRecord don't carry inlineParallelCapable.
• dashboard/.../Endpoints.tsx renders a "batch" badge on ep.batchCapable; add an "inline-parallel" (n/count) chip for ep.inlineParallelCapable.

User-visible regression to close: since #116 reclassified images.generate off batchCapable, DALL·E endpoints lose their old (incorrect) "batch" badge and currently show nothing. This issue restores a correct capability indicator. Depends on the EndpointRecord threading (see the [Detection] follow-up + core-scanner already populates the field).
