Hold @lobehub/ui at 5.49 while LobeHub's stable release needs it (#17531)

@lobehub/ui 5.50.0 dropped NeuralNetworkLoading, and LobeHub 2.2.18 still imports
it through a ^5.47.0 range with lockfile: false, so every fresh build now fails.
Upstream moved off it on main; the pin only applies while package.json still asks
for a 5.4x range, so it stops on its own with the next stable release.
