Riccardo Manfrin 8a43f4f943 [client] fix build: add ReapplyMatching to dedicated AllowedIPsRefCounter (#6935)
## Describe your changes

#6799 turned `AllowedIPsRefCounter` from an alias of the generic
`Counter` into a dedicated peer-aware type. A change merged in parallel
— `DefaultManager.ReconcilePeerAllowedIPs` (lazy-connection idle→wake
reconvergence) — calls `allowedIPsRefCounter.ReapplyMatching`, which
only existed on the generic `Counter`. Each PR built alone; the merged
`main` did not:

```
client/internal/routemanager/manager.go: m.allowedIPsRefCounter.ReapplyMatching undefined
```

Add `ReapplyMatching(pred, apply)` to the dedicated type, matching the
generic contract (keyed on the active/`Out` peer): it re-applies every
prefix whose currently installed peer satisfies `pred`, skipping
prefixes with no active peer (reconciled by the next
Increment/Decrement). Also update `reconcile_test.go` to construct the
counter via `refcounter.NewAllowedIPs` — the generic `refcounter.New`
return value is no longer assignable to the dedicated type.

Verified with `cd client && CGO_ENABLED=1 go build .` (the failing CI
step) and the `TestReconcilePeerAllowedIPs` / refcounter / routemanager
tests.
