Update docs for TON proof backend, Mini App fixes, and EVM wallet stub

PRD - TON Wallet Ownership Proof.md:
- Status updated from ready-to-implement -> backend-implemented.
- Added Implementation Status section documenting what is complete
  (challenge endpoint, tonProofService.ts, User model fields, 15 tests)
  and what remains (frontend proof wiring, verified badge).
- Acceptance criteria updated: backend items checked, frontend pending.

Handoff - Telegram Mini App Debug - 2026-05-24.md:
- New Implemented sections for session 3:
  - TON Wallet Ownership Proof backend (full detail of tonProofService,
    userController changes, User model fields, 15 unit tests).
  - Telegram Mini App shell dir="ltr" + smart displayName fallback.
  - Socket status suppressed on /telegram paths.
  - EVM WalletConnect stub card (disabled until project ID configured).
- Known Issues: TON proof updated to "frontend wiring pending";
  EVM WalletConnect section added with activation steps.
- Current Git State updated to Session 3.
