Ports all BLE timing reductions from payfrit-beacon-android (PRs #6/#9) to the iOS beacon app.

Changes (BeaconProvisioner.swift)

Timing Before After
Base write delay 0.5s 0.2s
Heavy write delay (frame select/type) 1.0s 0.4s
Large payload delay (UUID) 0.8s 0.3s
Response gate timeout 1.0s 0.5s
Per-write timeout 5.0s 2.0s
Global provisioning timeout 90s 30s
Read config timeout 15s 8s
Password retry delay 0.5s 0.2s
FFE2 reconnect delay 2.0s 1.0s
Connection retry backoff 1/2/3s 0.5/1/1.5s
Disconnect retry backoff 3/4/5s 1/1.5/2s
Read query delays 0.4s 0.2s
Reconnect resume delay 1.5s 0.5s
Final response wait 2.0s 1.0s

Same optimization strategy as Android: 40-60% reduction in total provisioning time.

DX-Smart beacons (the only ones we actively use) should see the biggest improvement.
