fix(deleted-project): Handle deleted Gitlab projects gracefully in project list and changelog

[M0nkeySan]

What

Previously, when trying to fetch projects that existed in our database but were deleted from Gitlab, the project list and changelog modal commands would fail entirely. This was because Promise.all would reject if any single project fetch failed.

Fix

Changes:

• Added error handling around individual project fetches
• Filter out non-existing Gitlab projects instead of failing
• Ensures commands continue working even when some projects are inaccessible

Conclusion

This makes the system more resilient by allowing operations to continue even when some referenced projects no longer exist in Gitlab.
