refactor: simplify UUID processing and standardize SchemaUtils usage

- Removed unnecessary UUID casting in repositories (`ExposedFunktionaerRepository`, `ExposedReiterRepository`, `ExposedVereinRepository`).
- Replaced `SchemaUtils.createMissingTablesAndColumns` with `SchemaUtils.create` in database configuration for consistency.
