chore: rework references for repo rename deploy-felhom-compose -> felhom-controller

Repo renamed on Gitea (admin/deploy-felhom-compose -> admin/felhom-controller).
Updates clone URLs, clone dirs, the customer bootstrap URL, build.sh, BUILDING.md,
README.md, CLAUDE.md, CONTEXT.md and TASK.md to the new name. No functional change:
Go module path and Docker image path (both already 'felhom-controller') untouched.
