feat: deleting stardance projects

[0xDracula]

my plan:

this PR adds support for deleting projects through soft-deletion. currently, soft_delete! exists but it's partially implemented, and devlogs need to be marked as deleted!

• soft_delete! (soft deleting devlogs)
• editing restore! to also restore devlogs
• UI

[0xDracula]

these queries were used for testing soft_delete!

for project & devlogs deletion:

p = Project.unscoped.find(PROJECT_ID); puts "Project: #{p.title} (Deleted At: #{p.deleted_at})"; devlog_posts = Post.unscoped.where(project_id: PROJECT_ID, postable_type: 'Post::Devlog'); puts "Total Devlog Posts: #{devlog_posts.count}"; devlog_ids = devlog_posts.pluck(:postable_id); deleted_devlogs = Post::Devlog.unscoped.where(id: devlog_ids).where.not(deleted_at: nil); puts "Soft-Deleted Devlogs: #{deleted_devlogs.count}"

for reposts deletion:

p = Project.find(PROJECT_ID); p.soft_delete!; repost_count = Post::Repost.unscoped.where(original_post_id: p.posts.pluck(:id)).where.not(deleted_at: nil).count; puts "Project Deleted. Hidden Reposts: #{repost_count}"

the old way was using

app/models/concerns/soft_deletable.rb

which only marks the project as deleted ignoring the devlogs & reposts

the new way marks project, devlogs & reposts as deleted
