Subject: [PATCH] [br-tracker] initialize `aMinAge` to `uint32_t::kMax`
 (#11963)

In `NetDataPeerBrTracker::CountPeerBrs()` method, the `aMinAge`
output parameter is a `uint32_t` but it was incorrectly
initialized to `NumericLimits<uint16_t>::kMax`.

This change corrects the initialization to use the
`NumericLimits<uint32_t>::kMax` to ensure the minimum age
calculation functions correctly over the full 32-bit range.
