Zhi Wei Jian 2bada5b678 feat(ble/bluedroid): reject LE re-pairing that weakens an existing bond 
Add smp_repairing_is_allowed() behind BT_BLE_SMP_HARDENED_REPAIRING so a
peer cannot replace an existing bond with one that has less MITM
protection, no Secure Connections, or a shorter key. Compare a preceding
Security Request against the pairing command AuthReq, not the
association-model result, and always allow first pairing.

A refusal keeps the stored bond. Pairing-failure erase is split by link
role: default is erase as Central and keep as Peripheral.

Closes BLERP (NDSS 2026) V3, V4 and V6.
