test(contrib/drivers/mariadb): add transaction, where, hook and ctx tests (#4720)

## Summary

- Port 28 transaction tests: Begin/Commit/Rollback, nested SavePoint,
transaction propagation (Required/Nested/NotSupported), timeout, panic
recovery, concurrent transactions
- Port 41 where-condition tests:
Where/WhereOr/WhereNot/WhereIn/WhereBetween, prefix handling, complex
AND/OR combinations, NULL checks, struct/map/slice parameter types
- Port 11 hook tests: HookSelect/HookInsert/HookUpdate/HookDelete for
both Model and raw SQL paths, hook chaining and context propagation
- Port 8 ctx tests: context propagation through Model/TX operations,
context-based logging with traceId verification

All tests are structurally identical to the MySQL driver baseline. SQL
syntax is standard and shared. Package and import references are adapted
for MariaDB.
