chore: remove mobile/ from monorepo, suspend CI mobile job

* chore: update exchange submodule to pex.network release + add shared images

Exchange submodule advanced to include:
- sweeper.js: TRC-20 JWT Bearer auth, DOT transferAll, PEZ-AH pre-fund
- docker-compose.yml: pex.network defaults for VITE_API_BASE_URL and SMTP_FROM
- .github/workflows/build-deploy.yml: pex.network build arg for web service

Shared images added: keziyakurd, kiwi_perwerde, kurdistan_assembly, pezkuwi, satoshi_qazi_muh

* chore: remove mobile/ from monorepo, suspend CI mobile job

Mobile app moved to /home/mamostehp/pwap-mobile (local, suspended).
Will be re-integrated when mobile development resumes.

- Removed mobile/ directory entirely
- Removed Mobile App job from quality-gate.yml so CI no longer blocks
