Prune the upstream Mini/QR mobile subsystem from POS

POS was forked from Ladill Mini and carried Mini's entire mobile/QR
subsystem (API, QR codes, wallet, payments, push, Afia) which polluted the
ladill_pos schema with 8 unused tables and left ~half the test suite red.

Remove the dead subsystem: Api/Mini/Qr/Public/Search/WellKnown controllers,
Mini/Qr/Afia/Notifications services, the 8 unused models, QrCodePolicy,
Support/Qr + Support/Events, the two mini: scheduled commands, the Mini/QR
view trees, and their (failing) tests. Empty routes/api.php (POS is web-only)
and strip dead schedules from routes/console.php.

Keep QrTeamMember — it is the platform team-membership model that POS's
SetActingAccount middleware and SSO login depend on for multi-account access.
Also keep notifications + personal_access_tokens (used by POS).

Drops 7 migrations (qr product/settings, mini_payments, push tokens); the 8
orphan tables are dropped from the live ladill_pos DB separately. Test suite
is green (8 passed) and all routes resolve.
