refactor(migrations): consolidar add_* en sus create_* (49 → 28)

Pliega las migraciones de "añadir/modificar columna" dentro de la migración create
de cada tabla, con esquema final idéntico (verificado por diff normalizado de columnas
+ índices y suite completa):
- users (locale, notes), projects (reference/external_reference_1/country),
  companies (apodo/estado/logo_path), layers (color; sin geojson_data),
  phases (fechas), features (status/responsible_user_id + sync + softDeletes),
  inspection_templates (phase_id), inspections (workflow + sync + softDeletes),
  issues (type + sync), progress_updates/media (sync), issue_tasks (overdue),
  permissions (group/description) y roles (description); soft-deletes en sus creates.
- Se mantienen las que dependen de orden/FK: add_profile_fields (users.company_id → companies)
  y update_inspections_feature_id_foreign (feature_id → features).
- Eliminado database/schema/mysql-schema.sql (obsoleto): las instalaciones nuevas
  ejecutan las migraciones; las BD existentes no se tocan. Regenerable con schema:dump.

Suite 75 passing. Esquema SQLite idéntico antes/después.
