Address review feedback on query cache unit tests (PR #5486 )

- test_pgsql_flush: flush() at start for clean state, assert == 10
- test_mysql_construction_and_flush: fix tautology (flushed == 0 ||
  flushed >= 0 is always true for uint64_t), double-flush to ensure
  empty cache, then assert == 0
- test_pgsql_purge_expired: use max_memory_size=1 instead of 1GB to
  force the purge path to actually run (3% threshold wasn't reached)
- test_pgsql_many_entries: fix misleading docstring claiming hash
  table distribution verification

Add Query Cache unit tests (Phase 2.3, #5475 )

Comprehensive unit tests for MySQL_Query_Cache and PgSQL_Query_Cache
covering 26 test cases across 11 test functions. Runs in <0.01s with
no infrastructure dependencies.

PgSQL_Query_Cache is used for most tests because its set()/get() API
is simpler (no MySQL protocol parsing required). The underlying
Query_Cache<T> template logic is identical for both protocols.

Test coverage:
- Basic set/get cycle with value verification
- Cache miss on nonexistent key
- User hash isolation (same key, different user_hash = miss)
- Cache replacement (same key overwrites previous value)
- Hard TTL expiration (expire_ms in the past)
- Soft TTL expiration (cache_ttl parameter to get())
- flush() clears all entries and returns correct count
- Set/flush cycle (entry retrievable then unretrievable)
- Stats counters (SET and GET via SQL3_getStats())
- SQL3_getStats() result format (2 columns, has rows)
- MySQL_Query_Cache construction, flush, and SQL3_getStats()
- purgeHash() eviction of expired entries (live entries survive)
- Bulk insert (100 entries) across 32 internal hash tables

Key implementation note: Query_Cache constructor requires a valid
Prometheus registry (GloVars.prometheus_registry). The test_init_
query_cache() helper creates one automatically.
