fix(test): retype petProfileSummary chain mock to satisfy tsc --project build

CI failed on PR #137 because `tsc --project .` (the build path used by the
Docker image) is stricter than `pnpm typecheck` was reporting during local
iteration — two TS2322 errors surfaced in the new mock:

  1. `chain.from = (table: { _name: string }) => ...` was assigned through
     a `Record<string, (...args: unknown[]) => unknown>` index signature,
     and `{ _name: string }` is not assignable from `unknown`.
  2. `chain.then = (onFulfilled?: (v: unknown[]) => unknown) => ...` was
     not assignable to the `PromiseLike<T>.then` signature TS now infers
     for the awaitable, because TS expects `onfulfilled` to also accept
     `null`.

Replace the proxy-based loose chain with a typed `ChainLike` interface so
the build typechecker is satisfied. Behaviour is unchanged — all 7 GRO-2014
regression tests still pass.
