Duplicate _translate_labels fallback, unreachable /eskaera/add-to-cart and
/eskaera/save-cart routes (the frontend cart is localStorage-only and uses
save-order), redundant pickup wrappers, unused pagination/count helpers and
fields, deprecated JS shims, and the already-empty checkout_summary.js and
i18n key/init leftovers.
Also drops 11 tests/*.py never wired into tests/__init__.py: three were
unimplemented placeholders (setUp with no assertions), and the other eight
had real assertions but were bit-rotted against the current schema (e.g.
res.partner.is_supplier no longer exists) — wiring them in surfaced 43
failures unrelated to this cleanup. Verified 0 failed/0 errors of 270 tests
both before and after.
