refactor(loyalty): remove the dead customer points and tokens code

First part of PC-601 (docs/prd-point-coin.md §10.7): the code that has
had no way in since balances moved to the wallet.

- The /marketing/customer-points and /marketing/customer-tokens routes
  were commented out; their 16 handler methods, the GamificationService
  methods behind them, and the validators, transformers, mappers and
  contract/model types only they used are gone.
- CustomerPointsProcessor loses its "not implemented" stubs; it keeps the
  customer app's balance, wallet and games endpoints.
- CustomerTokensProcessor and the customer points and tokens repositories,
  wired but no longer called by anything, are gone.

What stays until its preconditions are met: the customer_points and
customer_tokens tables and their entities, which cmd/wallet-migrate still
reads, and the /customer/points, /customer/tokens aliases and the
token_used / tokens_remaining fields, until the apps no longer use them.
