[Admin] Search for projects and show project details

[laushinka]

Admin page should allow searching of projects by entering the repo or the slug.

(The following screenshot is just a placeholder - this will need more design decisions)

Search

• sub-string match anywhere in the cloneUrl (assuming this is possible, and OK for DB performance)
• nice-to-have: match on slug

Search results

• list entries show name (link to project detail), cloneUrl (link to git provider)
• list ordered by created date
• list ordered by updated date

Project details

• page URL is /admin/projects/project-id
• name
• repository (from cloneUrl)
• incremental prebuilds (from settings)
• owner
• team
• created date
• list of prebuilds

Prebuild details

• page URL is /admin/prebuilds/prebuild-id
• same content (with prebuild log) as in projects UI
