Since `modules/context` has to depend on `models` and many other packages, it should be moved from `modules/context` to `services/context` according to design principles. There is no logic code change on this PR, only move packages. - Move `code.gitea.io/gitea/modules/context` to `code.gitea.io/gitea/services/context` - Move `code.gitea.io/gitea/modules/contexttest` to `code.gitea.io/gitea/services/contexttest` because of depending on context - Move `code.gitea.io/gitea/modules/upload` to `code.gitea.io/gitea/services/context/upload` because of depending on context (cherry picked from commit 29f149bd9f517225a3c9f1ca3fb0a7b5325af696) Conflicts: routers/api/packages/alpine/alpine.go routers/api/v1/repo/issue_reaction.go routers/install/install.go routers/web/admin/config.go routers/web/passkey.go routers/web/repo/search.go routers/web/repo/setting/default_branch.go routers/web/user/home.go routers/web/user/profile.go tests/integration/editor_test.go tests/integration/integration_test.go tests/integration/mirror_push_test.go trivial context conflicts also modified all other occurrences in Forgejo specific files
