Lightbox was previously a file-private component inside AttachmentImage
(used for enlarging chat image attachments). Extracted to a standalone
components/Lightbox.tsx so other surfaces can reuse the same dialog
without duplicating Esc/backdrop/body-overflow plumbing.
In SettingsPage's profile live-preview, the round avatar overlapping the
banner is now wrapped in a transparent button that opens the Lightbox
with the full-resolution avatar URL on click. Cursor switches to
zoom-in. Disabled when the user only has the initial-letter placeholder
(nothing meaningful to enlarge). Native button chrome (border, padding,
button-face background) is reset to keep the avatar circle's appearance
unchanged.
