agessaman b0cf29fb33 test(mqtt): extract + test remaining inline MQTT decision points (Phase 6) ...

Close the host-testable gaps named in Phase 6 of STABILITY_TESTABILITY_HANDOFF.md
by moving the last inline decision logic into the pure, host-tested policy seams:

- WiFi STA reconnect backoff: extract the inline ladder + wrap-safe timing from
  handleWiFiConnection() into MQTTConnectionPolicy::{wifiReconnectBackoffMs,
  wifiReconnectDue,nextWifiBackoffAttempt}. Behavior-preserving (elapsedMs is the
  wrap-safe form of the old ULONG_MAX branch); ladder/clamp/attempt-cap unchanged.
- Publication outcome pairing: name the (packet, raw) -> delivered contract as
  MQTTPacketQueuePolicy::queuedPacketPublished() and wire both queue-drain sites;
  partial success = completed, not retried.
- Freeze MQTTPublicationType enum values in a test (the bridge-side MQTTMessageType
  alignment is already enforced by a compile-time static_assert).

Adds host tests for all three (exact boundaries + millis() rollover). Native suite
green (13 dirs); non-PSRAM observer firmware smoke build compiles.

WebConfig batch/reboot/stop state-machine extraction and queue-orchestration
coverage remain open (tracked in the Phase 6 status).
