fix(k3s): increase SQL Server memory limits to prevent OOMKilled
Test and Deploy to k3s / test (push) Failing after 1m4s Details
Test and Deploy to k3s / deploy (push) Has been skipped Details 

- Memory limit: 384Mi → 768Mi
- Memory request: 256Mi → 512Mi
- MSSQL_MEMORY_LIMIT_MB: 340 → 512

Previous limits caused OOMKilled restarts during SQL Server startup.
