174240c13e fix: overhaul beacon discovery to match Android detection logic 
Major detection gaps were causing iOS to miss 7-8 out of 8-9 nearby DX beacons:

1. FFF0 service UUID was incorrectly mapped exclusively to BlueCharm.
   Android maps DXSmartProvisioner.SERVICE_UUID_FFF0 to DXSMART.
   Now checks device name to disambiguate FFF0 between DX and BlueCharm,
   defaulting to DXSmart (matching Android behavior).

2. Added DX factory default UUID detection (E2C56DB5-DFFB-48D2-B060-D0F5A71096E0).
   Android catches DX beacons by this UUID on line 130 of BeaconScanner.kt.
   iOS was missing this entirely.

3. Added Payfrit shard UUID detection — already-provisioned DX beacons
   broadcasting a shard UUID are now recognized.

4. Added iBeacon manufacturer data parsing with proper UUID extraction.
   Any device broadcasting valid iBeacon data is now included (not just
   those with minor > 10000).

5. Added permissive fallback matching Android lines 164-169: connectable
   devices with names are included even if type is unknown, so they're
   at least visible to the user.

6. Added FEA0 service UUID for BlueCharm (Android line 124).

7. Added "DX-CP" name pattern (Android line 138) that was missing.

Root cause: Android uses MAC OUI prefix 48:87:2D to catch all DX beacons
regardless of advertisement contents. iOS can't do this (CoreBluetooth
doesn't expose MAC addresses), so we compensate with broader iBeacon
UUID matching and more permissive device inclusion.

38b4c987c9 fix: address all issues from koda's code review 
🔴 Critical:
- DXSmartProvisioner: complete rewrite to match Android's new SDK protocol
  - Writes to FFE2 (not FFE1) using 4E4F protocol packets
  - Correct command IDs: 0x74 UUID, 0x75 Major, 0x76 Minor, 0x77 RSSI,
    0x78 AdvInt, 0x79 TxPower, 0x60 Save
  - Frame selection (0x11/0x12) + frame type (0x62 iBeacon)
  - Old SDK fallback (0x36-0x43 via FFE1 with 555555 re-auth per command)
  - Auth timing: 100ms delays (was 500ms, matches Android SDK)
- BeaconShardPool: replaced 71 pattern UUIDs with exact 64 from Android

🟡 Warnings:
- BlueCharmProvisioner: 3 fallback write methods matching Android
  (FEA3 direct → FEA1 raw → FEA1 indexed), legacy FFF0 support,
  added "minew123" and "bc04p" passwords (5 total, was 3)
- BeaconBanList: added 4 missing prefixes (8492E75F, A0B13730,
  EBEFD083, B5B182C7), full UUID ban list, getBanReason() helper
- BLEManager: documented MAC OUI limitation (48:87:2D not available
  on iOS via CoreBluetooth)

🔵 Info:
- APIClient: added get_beacon_config endpoint for server-configured values
- ScanView: unknown beacon type now tries KBeacon→DXSmart→BlueCharm
  fallback chain via new FallbackProvisioner
- DXSmartProvisioner: added readFrame2() for post-write verification

cfa78679be feat: complete rebuild of PayfritBeacon iOS from scratch 
100% fresh codebase — no legacy code carried over. Built against
the Android beacon app as the behavioral spec.

Architecture:
- App: SwiftUI @main, AppState-driven navigation, Keychain storage
- Views: LoginView (OTP + biometric), BusinessListView, ScanView (provisioning hub)
- Models: Business, ServicePoint, BeaconConfig, BeaconType, DiscoveredBeacon
- Services: APIClient (actor, async/await), BLEManager (CoreBluetooth scanner)
- Provisioners: KBeacon, DXSmart (2-step auth + flashing), BlueCharm
- Utils: UUIDFormatting, BeaconBanList, BeaconShardPool (64 shards)

Matches Android feature parity:
- 4-screen flow: Login → Business Select → Scan/Provision
- 3 beacon types with correct GATT protocols and timeouts
- Namespace allocation via beacon-sharding API
- Smart service point naming (Table N auto-increment)
- DXSmart special flow (connect → flash → user confirms → write)
- Biometric auth, dev/prod build configs, DEV banner overlay
