minor cleanup for go-next

[frzyc]

Describe your changes

• Update NextJS version to see if it improves dev performance (seems like it does not)
• Use the same SillyContext from @go/gi/ui, remove the one in @go/gi/ui-next
• Use a singleton for the PrismaClient to battle duplicate clients on reload while dev
• Test out weapons page for data connection between pages in SSR
