chore: rename gitea-projects-api → gitea-local-fork

The fork tracked by this derivation is no longer a single-feature
branch ("feat/projects-api") but the integration tip of Oleks's
local gitea fork ($HOME/projects/gitea, branch oleks/main), carrying
upstream/main + PR #37518 Projects REST API + a CI gate + fork-local
commits. Reflect the broader scope in the package and attribute name,
and document the local fork path + branch in the derivation header.
