feat: remove legacy project columns, old settings tables, and app_id defaults

Drop deprecated columns (live_deployment_id, is_rolled_back, depot_project_id)
from projects table. Delete environment_build_settings and
environment_runtime_settings tables/queries in favor of app-scoped equivalents.
Remove DEFAULT '' from app_id columns. Migrate all Go code to use app-scoped
queries: github_webhook, verify_handler, deployment_state, build, seed files.
