feat(match-history): expose executable and INI CRCs

[tintinhamans]

Add executable and INI CRC values to persisted match history and API responses.

---

• Store lobby exe_crc and ini_crc values when creating match-history entries
• Map both values as unsigned database columns
• Include both CRCs in all match-history response paths
• Update the baseline database schema with default values for existing records

---

Existing databases require the following schema update before deploying the service:

ALTER TABLE `match_history`
  ADD COLUMN `exe_crc` INT UNSIGNED NOT NULL DEFAULT 0,
  ADD COLUMN `ini_crc` INT UNSIGNED NOT NULL DEFAULT 0;
