Pull request overview
Implements IEEE 1905.1 backhaul steering support by introducing a new command event subtype and an EasyMesh RBUS method that forwards steering requests into the controller/app event flow, where the EasyMesh app triggers the mesh STA connection state machine using the requested target BSSID.
Changes:
- Added new command subtype
wifi_event_type_backhaul_steer(enum + string conversion). - Ensured the controller command handler does not process this event (so it can be consumed by apps).
- Added RBUS method
Device.WiFi.EM.BackhaulSteerand EasyMesh app handling to locate the target mesh STA VAP by MAC and trigger mesh-ext reconnect logic with the requested BSSID.

| File | Description |
|---|---|
| source/core/wifi_events.c | Adds string mapping for the new backhaul steering command subtype. |
| source/core/wifi_ctrl_queue_handlers.c | Excludes the new subtype from controller-side command handling so it can be forwarded to apps. |
| source/apps/em/wifi_em.h | Adds RBUS method name constant for backhaul steering. |
| source/apps/em/wifi_em.c | Implements RBUS handler + event processing to map request to mesh STA VAP and trigger mesh-ext state machine with target BSSID. |
| include/wifi_events.h | Adds the new command subtype to the global event subtype enum. |

Add rbus handler and event processing for backhaul steering requests received from the EasyMesh agent. On receipt, the target mesh backhaul STA VAP is looked up by MAC address and the connection state machine is triggered with the target BSSID.
