feat(backend): complete Modules 2 + 3 (geo + user management)

Module 2 — Geographic Data: PSGC tables (regions/provinces/cities/
barangays) with native geometry(polygon|point, 4326) columns; cascading
dropdown endpoints; ST_Contains-based GPS resolution; service-area CRUD
with barangay attach/detach; SamplePsgcSeeder + psgc:import command.

Module 3 — User Management: 5 role-specific profile tables (driver/
helper/scanner/store_partner with verification_status + rejection
reason); profile auto-created on register; admin user CRUD with
filters/pagination, suspend/activate, profile approve/reject;
self-service /me + /me/profile with role-aware validation that blocks
self-approval and resets rejected profiles to pending on resubmit.

69 feature tests passing.
