test(guard): widen the client-bundle guard to every "use client" entry point (#10692) (#10700)

The guard shipped with #10695 watched two hand-picked modules. It now walks the static
import graph from all 753 "use client" files in src/ (plus the two originally pinned
entries), so the invariant is verified across the repo instead of where someone
remembered to look. Full sweep runs in ~750ms.

Two exclusions make that practical:

- `import type` is not an edge — TypeScript erases it before the bundler sees it.
  Counting type imports turns 3 real findings into 29; a guard that cries wolf gets
  switched off.
- Dynamic `import()` is still not followed. It does not break a bundle edge (that was
  tried for #10692 and failed) but it does move the module into a chunk the browser
  fetches on demand, which is a legitimate boundary.

The widened sweep immediately found what the narrow one could not: five value-form
imports of `db/batches` / `db/files` across three files under dashboard/batch, each
reaching db/core → the SQLite driver. All five bind only interfaces (BatchRecord,
FileRecord) used in type position, so the compiler was eliding them and the build stayed
green — the same latent shape as #10692 before #10647 removed the toolchain's tolerance.
Marking them `import type` makes the elision explicit instead of incidental.
