- Filter out COMMENT type relations, only show REFERENCE type
- When editing a memo, only show relations where current memo is the source
- Pass memoName through EditorMetadata to RelationList for filtering

Add ListMemoComments to public endpoints whitelist so unauthenticated
users can see public comments. The service layer already filters
comments by visibility (only PUBLIC for guests).

Fixes #5471

- Fix linting issues and address testcontainers deprecation in store/test/containers.go
- Extract MemosStartupWaitStrategy for consistent container health checks
- Refactor migrator_test.go to use a consolidated testMigration helper, reducing duplication
- Add store/test/Dockerfile for optimized local test image builds

Reverts only the system_setting → instance_setting rename related changes from commit d326c710.
Keeps the resource → attachment rename changes intact.

- Reverts table name back to system_setting in all database drivers (MySQL, PostgreSQL, SQLite)
- Removes migration files for the system_setting rename
- Reverts LATEST.sql files to use system_setting table

This fixes an issue where the theme selector on the login screen would not update its display value after selection because the component was not re-rendering. Added local state to track the current theme. Validated that this pattern is unique to the unauthenticated context.
