docs(issues): address Copilot review comments on PR #1702

- project-words.txt: sort newly-appended words alphabetically
- 1525-06: fix double semicolon typo in MIGRATOR.run() snippet
- 1525-07: replace "reversible" with "tracked as a forward schema
  change" — sqlx has no down/rollback migrations
- 1525-08: fix migration-1 valid_until type (BIGINT → INTEGER to
  align with other backends; migration-4 widens to BIGINT)
- 1525-08: fix Error::migration_error argument order (e, DRIVER) →
  (DRIVER, e) to match the signature used throughout 1525-06

 database columns from `INTEGER` (32-bit, MySQL) to `BIGINT` (64-bit), delivered as a versioned
