// ── Admin · Users: the core half of /admin/users/:id ───────────────────────
//
// `getUser` lived in usersShard.controller.js until Phase 2 PR 4, purely because
// the detail page it backs is mostly shard panels. MODULE_SYSTEM.md §1.9 called
// that out as core semantics that ended up in the UO controller by proximity, and
// it moved back to admin.controller.js — the shard panels around it are now an
// extension slot, so this handler has to stand on its own when they leave.
//
// Point the DB at a closed port BEFORE requiring anything that builds the pool,
// so any stray query fails fast instead of hanging the runner.
