Clean up development artifacts and obsolete code

Dependencies:
- Remove unused bcrypt package (only bcryptjs is used)
- Remove @types/bcrypt (only @types/bcryptjs needed)

Scripts cleanup:
- Delete migration scripts (one-time use, already applied):
  - add-mqtt-tables.js
  - add-parent-user-column.js
  - migrate-device-ownership.js
  - fix-acl-topic-patterns.js
  - update-acl-permission.js
- Delete personal test/debug scripts:
  - reset-joachim-password.js
  - test-joachim-password.js
  - check-admin.js
  - check-user-password.js
  - test-password.js
  - test-device-access.js
  - test-user-visibility.js
- Move change-mqtt-admin-password.sh to scripts/ directory

Code cleanup:
- Remove debug console.log statements from:
  - app/api/locations/ingest/route.ts
  - components/map/MapView.tsx (2 debug logs)
  - lib/db.ts
