Subject: [PATCH] fix: repair auth method check, pagination stub, shared type
 field, and imports

- Implement paginate() in shared package (page slicing, total/totalPages,
  out-of-range and empty-array handling)
- Fix case-sensitivity bug in auth middleware public-method allow-list so
  POST /users is treated as public
- Rename User.userName -> username in shared types to match call-sites and tests
- Add missing badRequest import in users route handler
- Add bun-types to tsconfig so bun:test/process globals resolve under tsc
