build: align @trpc/* on a single workspace version

@trpc/client resolved to 11.16.0 in some packages while @trpc/server
resolved to 11.17.0 in others, tripping the exact-version peer check.
Update every @trpc/* range in-range so the whole workspace resolves to
one version (11.18.0); install is peer-warning-free again.
