feat: R3b wire drr_emergency_pool_kb / drr_recovery_log_size from FUCK

Browse Source 
- drr_apply_config(pool_kb, log_size) before drr_init; pool_limit clamped to compile-time 64KB static pool (min sub-buffer layout enforced, defaults kept on bad values); recovery log size clamped to remaining pool
- verified in QEMU: pool_kb=32 -> pool_limit=0x8000, log_capacity=0x80, boot continues (.build_tmp/qemu_serial_r3b.log)
