refactor(projects): Unify linked projects modal table columns

[ansonnchan]

Issue #1505

Hi @deo002 , I've opened a PR for the "link projects modal" subtask of this issue.

Scope covered:

• src/components/sw360/LinkedProjectsModal/LinkProjectsModal.tsx
• src/app/[locale]/projects/components/LinkProjects.tsx

Summary:

• Unified duplicated linked-project table column logic used by both components
• Added a shared column implementation file: src/components/sw360/LinkedProjectsModal/linkedProjectsColumns.tsx
• Kept existing behavior as is

Validation done locally:

• pnpm exec biome check
• pnpm build

I verified commit metadata is correct (author/committer: ananryry180@gmail.com, commit: dc8325f).
I’m currently fixing Eclipse account linkage for ECA and will update once validation recognizes my GitHub account (ansonnchan).

Hey @ansonnchan !
The issue linked to this PR i.e #1505, where the point 5 you were trying to solve, doesn't align with the expected solution.
The issue is to remove the duplicate component.
In simpler terms, there are 2 link projects modal where only one is sufficient. Try to remove one of them, and cascade these changes to all the places, wherever the link project modal is used.

Note : As the link project modal is being used more than one place, it would be great to keep the component under src/components/sw360
