fix: improve robustness and security in database restore flows

- Add null checks for server instances in restore events to prevent errors
- Escape S3 credentials to prevent command injection vulnerabilities
- Fix file upload clearing custom location to prevent UI confusion
- Optimize isSafeTmpPath helper by avoiding redundant dirname calls
- Remove unnecessary --rm flag from long-running S3 restore container
- Prioritize uploaded files over custom location in import logic
- Add comprehensive unit tests for restore event null server handling
