feat: add comprehensive wireless client tracking and monitoring

Implements real-time wireless client monitoring with historical tracking,
LiveView UI, proactive alerting, and cross-browser e2e tests.

Phase 1: Historical Tracking
- Add TimescaleDB hypertable for wireless_client_readings
- Batch insert client metrics every 60 seconds from DevicePollerWorker
- 90-day retention with compression after 7 days
- Continuous aggregates for hourly (1 year) and daily (5 years) rollups

Phase 2: LiveView UI
- Add wireless tab to device detail page
- Real-time client list with PubSub updates
- Signal strength and SNR badges with 5-level thresholds
- Display MAC, IP, subscriber, TX/RX rates, distance, uptime
- Subscriber matching via device_subscriber_links
- Empty state handling

Phase 3: Proactive Alerting
- WirelessInsightWorker runs every 5 minutes via Oban cron
- 4 insight types with auto-resolution:
  * wireless_signal_weak: < -75 dBm (warning), < -85 dBm (critical)
  * wireless_snr_low: < 15 dB (warning), < 10 dB (critical)
  * wireless_ap_overloaded: > 50 clients (warning), > 75 clients (critical)
  * wireless_client_missing: expected subscribers not connecting
- Hysteresis thresholds prevent alert flapping
- Multi-organization isolation with proper deduplication

Code Quality:
- Refactored reload_current_tab_data to reduce cyclomatic complexity
- Combined double Enum.filter into single pass for efficiency
- Fixed length/1 comparison to use empty list check
- All Credo checks passing

Testing:
- 28 unit tests (ExUnit) - 100% passing
- 15 e2e tests (Playwright) - 100% passing across chromium/firefox/webkit
- Total: 73 tests, all passing
