fix(packages): declare runtime imports as production dependencies

@ekklesia/module-sdk imports drizzle-orm at run time but declared it
only as a peer and a development dependency. A workspace package is
linked into its consumers as a directory, so its imports resolve from
its own node_modules, where a consumer never satisfies a peer; a
production install omits development dependencies. In the production
image this made every module with a schema fail: the API exited at
startup and Doctor reported NOT READY.

- Move drizzle-orm to module-sdk's dependencies, keeping the peer.
- Move react to @ekklesia/ui's dependencies, keeping the peer. The new
  guard flags it the same way; it is bundled at build time today, so
  it was not a live failure. Both lockfile entries keep the identical
  resolution, so nothing new is installed and the shell bundles still
  contain one React.
- Add the boundary rule runtime-imports-are-production-dependencies:
  code a package ships (src/, bin/, excluding tests and .d.ts) must
  declare every runtime import in dependencies or optionalDependencies.
  Type-only imports are exempt; .tsx/.jsx implies react (automatic
  JSX runtime). Fixtures cover peer-only, dev-only, JSX, undeclared,
  and the accepted cases.
