add game tracker with owned pokemon data and call of duty mastery

Fold catchemall into /projects/game-tracker (old URL redirects) and add
Call of Duty tracking for Black Ops through WWII.

- Pokémon catalog is now owned: locations, encounters and per-game
  evolution methods are built from the pinned PokéAPI snapshot and seeded.
- Pokémon you can evolve or breed in a game count as obtainable; mythicals
  without another route are marked event-only.
- Detail dialog with evolution chain and where to find it, location pages
  with admin notes and pictures, and admin corrections that survive reseeds.
- Call of Duty weapons, milestones and Steam achievements per game, with
  derived Diamond / Dark Matter / Solar / Black Sky / Chrome tiers.
- New migration (db:migrate:game-tracker), seeds (db:seed, db:seed:cod) and
  deploy preflight checks for them.
