test: add Phase 0 GL characterization safety net

Browse Source 
Golden-master snapshot harness (GLSnapshot / assert_gl_snapshot) plus 12
characterization scenarios for Sales and Purchase Invoice (basic, taxes,
multi-currency, returns, round-off, discount accounting, advance, POS).
Locks current GL Entry output so the upcoming GL pipeline refactor
(composer / validator / sink) can be verified byte-identical.

Regenerate goldens with REGEN_GL_SNAPSHOTS=1.

"""Golden-master snapshot harness for GL Entry characterization tests.
Captures the General Ledger entries produced by a submitted voucher in a
normalized, deterministic form and compares them against a stored golden
snapshot. Volatile fields (name, creation, voucher number) are stripped so the
snapshot is stable across runs.
This is the Phase 0 safety net for the accounts/controller refactor: every
later phase must keep these snapshots byte-identical. Regenerate goldens with::
