-- Consolidate commit_journal_entry to a single 4-argument signature with defaults.
--
-- History:
--  - 20260402100200 created the canonical 2-arg (p_company_id, p_entry_id) version.
--  - journal_entry_commit_metadata added commit_method + rubric_version columns and
--    created a 4-arg overload via CREATE OR REPLACE; because the signature differs
--    from the 2-arg, both versions coexisted in prod, producing the
--    "Could not choose the best candidate function" ambiguity error on 2-arg calls.
--
-- Final state after this migration: only the 4-arg-with-defaults signature remains.
-- Callable with either 2 or 4 named args (defaults fill in the rest), so both the
-- currently-deployed 2-arg caller and the post-commit-metadata 4-arg caller work.
--
-- Idempotent: safe on any of the possible prior states (both, 2-arg only,
-- or 4-arg only). Columns commit_method / rubric_version are assumed to exist
-- (created earlier in the journal_entry_commit_metadata migration).
