Jordi Enric 93b5ae71bf chore: remove unused useProjectUsageStats hook (#48792) ...

## Problem

`useProjectUsageStats`
(`apps/studio/hooks/analytics/useProjectUsageStats.tsx`) has no
importers anywhere in the codebase — dead code, and it also still
queries BigQuery directly (`logs.all`, no OTEL path), which would've
made it another gap in the reports→ClickHouse migration if it were ever
wired up.

## Fix

Deletes the file. Confirmed nothing imports it, and none of its own
imports (`useFillTimeseriesSorted`, `useTimeseriesUnixToIso`,
`genChartQuery`, `EventChart`) become unused as a result — all are still
used elsewhere.

## How to test

- `pnpm tsc --noEmit` — no errors referencing the removed file.
- `pnpm vitest run hooks/analytics` — 28 tests pass, no breakage.
