Claude 323b30ea68 refactor(teleprompter): drop code that was not earning its keep ...

Review pass over the view.

Removed: estimateWordsPerLine and linesPerMinuteToWordsPerMinute, written for
a words-per-minute readout that was never built; play and pause on the
controller, which nothing outside the hook called; and three constants that
were exported but never imported.

The tick function was being reassigned to a ref on every render, which is a
side effect during render. It only ever touched refs and state setters, so it
is now a stable callback and the ref is gone.

The synthetic contentKey string is replaced by the memoised blocks array it
was standing in for. It was also a dependency of the ResizeObserver effect,
which tore the observer down and rebuilt it for no gain: the observer already
covers every reflow that changes the document.

ScriptBlock was memoised but never actually memoising, because the parent
built its ref callback inline and handed it a new identity every render. That
also churned the follow map, unregistering and re-registering every block. The
id is now bound inside the block against a stable callback.

Tests: dropped six that asserted arithmetic identities or wrapped clamps
rather than behaviour, and added three for branches that were untested,
group titles across and back into a group, and a heading with no cue.
The e2e rewind assertion waited 600ms for an eased scroll that needs about
900ms from a nudge and a second from the bottom of a long script; it now
polls. The navigation menu assertion raced app hydration and now waits for
the view, as the existing navigation tests do.
