Shaky reads become visible and clearable on the Titles page

The badge counted lines nothing on the page identified. Each shaky line
(vision confidence below high, nothing verified yet — the badge's exact
predicate, served per-line so page and badge can't disagree) now shows
a dashed gold "shaky read" chip, a filterbar toggle shows just them,
and a "✓ looks right" button confirms a correct read in one click —
recorded as a confidence-high edit record, so verification is as
durable as any other curation and, unlike a real edit, re-queues
nothing. Saving an unchanged edit form on a shaky line counts as
confirming it. Help's chip legend explains the chip and its three ways
to clear (confirm, edit, or a BGG match).
