docs: complete code-reality alignment for remaining docs + reconcile issue set

Remaining docs updated to match code (the docs that the first pass had not covered):
- Flows: Chat, Referral, Rating, Registration, Google OAuth, Negotiation, Payout,
  Trezor Safekeeping — corrected endpoints, socket events, status enums, auth gaps
- API Reference: User API, Trezor API — admin route prefix/verb/status corrections,
  added undocumented endpoints (ton-proof challenge, profile email verify,
  GET /trezor/account, POST /trezor/verify-operation)
- Data Models: Chat, Notification, Payment, PointTransaction, User — corrected
  enums (PaymentProvider, escrowState, PointTransaction.type, User.status),
  90-day notification TTL, soft-delete semantics, wallet fields

Trezor "zero frontend" finding (audit C31/C32) corrected as STALE:
- Verified current code HAS a full frontend Trezor implementation (admin/trezor
  page, TrezorSettingsView, trezorConnector via @trezor/connect-web,
  TrezorSignDialog, actions/trezor.ts building the {message,signature} object)
- Fixed Trezor Safekeeping Flow doc (removed false "no frontend" warnings)
- Reclassified ISSUE-012 as invalid/superseded with explanation

Issue set reconciled to a single canonical numbering (ISSUE-001..054):
- Adopted the comprehensive 51-issue set (long-slug, fully indexed)
- Removed 35 superseded short-slug duplicates from the first pass
- Removed a duplicate ISSUE-046 file
- Added 3 issues the 51-set lacked: ISSUE-052 (completed-not-counted-in-stats),
  ISSUE-053 (axios 401-only interceptor), ISSUE-054 (rate limiter counts all attempts)
- Regenerated Issues Index: 53 open (14 critical, 39 major) + 1 invalid

 The core identity document for every actor in the marketplace: buyers, sellers, and admins. Stores credentials (password + WebAuthn passkeys), profile/preference data, referral bookkeeping, point balances, and a soft-delete status flag. Almost every other model carries an `ObjectId` reference back to `User`, so this collection is the relational hub of the system.

+> [!note] Email change re-verification
+> When a profile update (`PUT /api/user/profile`, `userController.updateUserProfile`) changes `email` to a new value, the controller sets `isEmailVerified = false`, generates a **6-digit** `emailVerificationCode` (valid 15 minutes), stores it on `emailVerificationCode` / `emailVerificationCodeExpires`, and emails the code to the new address. The user must then confirm via `POST /api/user/profile/email/verify` (or request a new code with `POST /api/user/profile/email/resend-verification`).
+
+> [!note] Wallet ownership proof
+> `PATCH /api/user/wallet-address` accepts both EVM and TON wallets. EVM addresses require an EIP-191 signature (`ethers.verifyMessage`); TON addresses are format-validated and may include an optional TonProof. A successful proof sets `profile.walletProofVerified = true` and `profile.walletProofTimestamp`.
