Initial implementation of ammo price tracker
Phoenix 1.8 app that scrapes ammunition retailers (Lucky Gunner,
SGAmmo) for price data and displays historical price trends.
- Data model: retailers, calibers, products, price snapshots
- Scraper infrastructure with Req, Floki, realistic browser headers
- Oban-scheduled scrape jobs (every 4h with randomized delays)
- LiveView pages: homepage with category cards, caliber detail with
price table, Chart.js price history, and price stats banner
- 18 seeded calibers across handgun/rifle/rimfire/shotgun categories
- 77 tests
