## Summary
- Normalize all file paths with `path.resolve` instead of `join` to
properly handle `..` segments in file path inputs
- Add `assertPathIsWithinStorage` guard on all write, delete, move,
copy, and existence-check operations
- Introduce `ACCESS_DENIED` exception code with i18n-ready user-friendly
message
- Read path already had realpath-based validation; updated its error
code to `ACCESS_DENIED` for consistency
## Test plan
- [x] Typecheck passes
- [x] Lint passes
- [x] Manual: verify file upload/download still works with valid paths
- [x] Manual: verify `../` in file paths is rejected with ACCESS_DENIED

# Backfill application package files for custom and standard apps
- Backfill `package.json` / `yarn.lock` (and related fields) for
existing workspaces; new standard/custom apps get default dependency
files.
- Default package files under
`application/constants/default-package-files/`; util with hardcoded
checksums (comment on how to regenerate).
- New **FileFolder.Dependencies** for app dependency files;
**writeFile_v2** accepts optional `queryRunner` for transactional
writes.
Usages:
- **Upgrade command** `upgrade:1-17:backfill-application-package-files`:
standard/custom apps → default files; other apps → from logic function
layer.
- **Workspace creation**: create workspace with
`workspaceCustomApplicationId` first, then create application (enables
same-transaction insert). Migration makes workspace/application/file FKs
deferrable.
