test: update test suite for git-gate manifest redesign (PRD 0047)

- fixtures.py: fixture_with_git_dict uses git-gate.repos + url/identity/host_key
- test_manifest_git: rewrite to use git-gate.repos; replace duplicate-name
  test (names = dict keys, always unique) with two-repos-different-hosts test
- test_manifest_git_user: _manifest → git-gate.user; update error message assertions
- test_manifest_agent_git_user: git → git-gate throughout; repos rejection test
- test_manifest_extends: git.remotes/git.user → git-gate.repos/git-gate.user
- test_provision_git: IP test updated — no host alias, single insteadOf
- test_compose: git.remotes → git-gate.repos + new field names
- test_docker_provision_git_user: git.user → git-gate.user
- test_git_gate: inline manifest dict updated to git-gate.repos
- test_smolmachines_provision: git_json → git_gate_json; remove _remote_host
