[NGAP] Fix incorrect AMF Set ID type (uint8 → uint16) causing AMF lookup failure

Browse Source 
- Corrected AMF Set ID data type in ngap_gNB_nnsf_select_amf_by_amf_setid() from uint8_t to uint16_t.

- AMF Set ID is a 10-bit field as per 3GPP TS 38.413 §9.3.3.12.

- The incorrect data type caused truncation for AMF Set IDs >255, leading to lookup failures during RRC reestablishment.

- Verified successful reestablishment with large AMF Set IDs after the fix.

Reason for fix: AMF lookup using AMF Set ID was failing because the 10-bit AMF Set ID was truncated to 8 bits.

Closes #1012
