fix(nvim): correct popup rendering for bullets and LSP docs

RenderMarkdownBullet now uses fg only (no bg) so list bullets adopt the
window background instead of painting Normal's bg as a mismatched box in
popups. open_floating_preview is wrapped to widen hover/signature docs to
the 120-col line-length convention so long signatures wrap less.
