## Description

<!-- SECTION:DESCRIPTION:BEGIN -->
Fix final Convex typecheck blockers after adding usageEvents and external screenshot persistence. This includes updating generated Convex API references if required and making screenshot blob storage type-valid without changing runtime behavior.
<!-- SECTION:DESCRIPTION:END -->

## Acceptance Criteria
<!-- AC:BEGIN -->
- [x] #1 pnpm exec convex codegen --dry-run --typecheck enable exits 0
- [x] #2 pnpm exec tsc --noEmit exits 0 or reports only documented unrelated pre-existing issues
- [x] #3 pnpm test remains green
<!-- AC:END -->

## Implementation Plan

<!-- SECTION:PLAN:BEGIN -->
1. Reproduce Convex typecheck/codegen failures
2. Regenerate Convex API if required
3. Fix screenshot Blob typing with minimal runtime-neutral change
4. Re-run Convex typecheck, tsc, pnpm test
5. Leave task In Progress until Matthias confirms Done

## Implementation Notes

<!-- SECTION:NOTES:BEGIN -->
Verification/results:
- Reproduced with `pnpm exec convex codegen --dry-run --typecheck enable` outside sandbox after pnpm sandbox DB failure; initial result failed with TS2339 `internal.usageEvents` missing and TS2322 `Uint8Array<ArrayBufferLike>` not assignable to `BlobPart` in convex/auditGenerationAction.ts.
- Ran `pnpm exec convex codegen` outside sandbox; generated convex/_generated/api.d.ts now includes usageEvents.
- Applied minimal ownership-scoped Blob typing fix in convex/auditGenerationAction.ts by wrapping screenshotBytes with `new Uint8Array(screenshotBytes)` before Blob storage.
- `pnpm exec convex codegen --dry-run --typecheck enable` exits 0.
- `pnpm exec tsc --noEmit` exits 2 only because of unrelated pre-existing v2_elemente/* errors (missing local generated modules/imports and implicit any issues); no TASK-41/convex/auditGenerationAction.ts errors remain. Per user instruction, v2_elemente fixes were not touched.
- `pnpm test` exits 0: 363 tests passed, 0 failed.
