fix(ci): correct print_tags typo, add postinstall step to server-ci

- client-release.yml: inputs.print_tags -> inputs.tagName (tagName was
  the actual workflow_dispatch input, so tagName always fell back to
  the default 'v__VERSION__' string)
- server-ci.yml: pnpm install -> pnpm install --frozen-lockfile
  --ignore-scripts; add 'pnpm run postinstall' step before typecheck
  and lint so nuxt prepare + prisma generate + buf generate actually run
