Restore the Catlab helpers that DataMigrations relies on under Catlab 0.17, including pointed schema handling, free-graph mapping, ACSet functor materialization, and Yoneda parsing updates.\n\nCo-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Summary
While validating DataMigrations.jl against Catlab 0.17.5, a handful of helpers that DataMigrations and downstream rewriting code depend on were either missing or had subtly changed behavior. This PR restores those helpers so that DataMigrations.jl (and packages layered on top of it such as AlgebraicRewriting.jl and AlgebraicABMs.jl) compose cleanly against 0.17 without requiring downstream forks.
Changes
FinCatPres.jl: restore the pointed-schema handling andFreeCatGraphmapping that DataMigrations' conjunctive / representable migrations rely on.ACSetFunctors.jl: materialize ACSet functors so downstream data-migration pipelines can enumerate / apply them as expected.Yoneda.jl: align the Yoneda embedding parser with the restored pointed-schema API.FreeGraphs.jl/CoproductCats.jl: small fixups exposed by the above.Testing
Context
This is one of two small Catlab 0.17 follow-ups needed to unblock the AlgebraicJulia downstream stack. The second (composable-pair construction with mixed ACSet transformation types) is submitted separately as a companion PR.
