Videos rows are created by `tapir run`, not when a YouTube account is
connected, so a freshly-connected account correctly shows an empty list —
but the old empty state ("No videos yet") gave no clue why or what to do.
Split it on whether the user has any connection:
- connected, no videos: a distinct accent callout telling them to run
`tapir run` to discover subscriptions.
- not connected: a prompt with a Connect YouTube button.
handleList fetches connections only when the list is empty. Includes
web-shot captures of all three states under docs/ux-review/fixes/.
