fix(web): rename storageUsagePie helper to storageUsageSlices to avoid macOS case-collision with StorageUsagePie.tsx (#1483)

Since #1383 renamed the helper to storageUsagePie.ts, the same directory
contained both StorageUsagePie.tsx and storageUsagePie.ts. On case-insensitive
filesystems (macOS), extensionless imports of the component resolve to the
helper because '.ts' is tried before '.tsx' and 'StorageUsagePie.ts' matches
'storageUsagePie.ts' case-insensitively, breaking typecheck and component
tests on macOS. Linux CI is unaffected.

Renames the helper (and its test) to storageUsageSlices.ts, which cannot
collide, and updates the two importers. Fixes #1482.
