Extract counters API from global store into dedicated module (#2897)

This refactor moves the counters helpers out of
`frontend/app/store/global.ts` into a dedicated `counters.ts` module,
and updates existing call sites to import from the new location. The
goal is to keep `global.ts` focused on global store/state concerns while
preserving current counters behavior.

- **Module extraction**
  - Added `frontend/app/store/counters.ts` containing:
    - `counterInc(name, incAmt = 1)`
    - `countersClear()`
    - `countersPrint()`
  - Moved logic unchanged from `global.ts`.

- **Global store cleanup**
- Removed counters state/functions from `frontend/app/store/global.ts`.
  - Removed counters exports from `global.ts`’s export surface.

- **Call site updates**
  - Updated imports to use `@/store/counters` in:
    - `frontend/app/block/block.tsx` (`counterInc`)
    - `frontend/wave.ts` (`countersClear`, `countersPrint`)

```ts
// before
import { counterInc } from "@/store/global";

// after
import { counterInc } from "@/store/counters";
```
