Add PiP overlay example recipes (#132)
Self-contained examples for the PiP overlay API (POST /api/pip), each
with a CSP-safe query-param overlay (external JS), config.example.json,
zero runtime deps, an offline test, and a README:

- PIP-Announce-Broadcast    manual one-shot message to a screen/group
- PIP-Weather-Widget        Open-Meteo current conditions (keyless)
- PIP-Air-Quality           Open-Meteo US AQI widget (keyless)
- PIP-Crypto-Ticker         CoinGecko price strip (keyless)
- PIP-News-Ticker           scrolling RSS/Atom headlines
- PIP-Room-Status-Calendar  ICS-driven Available/Busy room sign
- PIP-Event-Countdown       client-side countdown, auto-clears at zero
- PIP-Welcome-Board         rotating welcome/birthday cards from CSV
- PIP-Fundraiser-Thermometer goal-progress bar from local/URL JSON
- PIP-QR-Rotator            rotating QR codes, encoded client-side
- PIP-Incident-Webhook      event-driven: red on firing, clear on resolved

Also includes the CAP-AU (NSW RFS) and US NWS/NOAA emergency-alert
monitors that push expiry-aware PiP overlays.
