feat(web): "Retrying later" badge for rate-limited videos

A discovered-but-unsummarized video whose caption fetch was rate-limited now
shows a passive ⏳ "Retrying later" chip (dim CharmDim styling, not the accent)
instead of the Summarize button — the user cannot fix a 429, the runner retries
automatically once the backoff window expires. Regenerated views_templ.go.
