lukaszraczylo 2c9b0a499f fix(memory, connection): two data-race/counter defects
1) connection_pool.go: GetConnectionStats read lastRecoveryAttempt (a
multi-word time.Time) without any lock while checkAndRecover wrote it
under recoveryMutex -> data race on live admin API endpoints. Snapshot it
under recoveryMutex (the writer's lock). Regression test
TestGetConnectionStatsRace drives the read path concurrent with the locked
write under -race.

2) cache/memory memory.go: Cache.Get expired path used an unconditional
Delete + atomic decrement, so concurrent Gets on the same expired entry
each decremented entryCount/memoryUsage -> permanent negative drift. Use
LoadAndDelete-with-guard (as evictOldest/evictToFreeMemory already do) so
only the goroutine that actually removes the entry decrements. Regression
test TestMemoryCacheConcurrentGetOnExpiredEntry_CountersConsistent.
