mappu 90cd2b6440 api: remove oldestCommit support
For codesite-migrated repositories, looking at the oldest commit is
preferable to determine the "create date". But for forked projects,
looking at the oldest commit is incorrect for when we started the project
If inferring the real create date has to be manual, then let's rely on
the Gitea metadata - it's faster and can be modified by hand if needed
