feat: structured logs /api/markets

[Opulencechuks]

Closes #389

Description

This PR addresses the backend issue for the GrantFox FWC26 campaign (Stellar Wave) by implementing structured access logs on /api/markets with correlation IDs.

Changes Made

• src/middleware/accessLog.ts: Updated the middleware logic to explicitly match the /api/markets route prefix and emit logs under the specific markets_access_log name. The logic correctly preserves correlation IDs utilizing the current priority chain and fallback mechanisms.
• src/routes/markets/index.ts: Integrated the accessLog middleware at the top level of the router to guarantee all market routes are correctly logged with correlation IDs before rate-limiting or sub-routing.
• tests/usersAccessLog.test.ts: Added focused unit tests validating the /api/markets path and verifying that the correct markets_access_log is emitted with correlation IDs and other necessary metadata.

Acceptance Criteria

• Implementation matches the description.
• Tests added and passing (with > 90% coverage on changed lines).
• Code review approved.
• Docs updated (inline comments matching the updated behaviors).

Technical Notes

• Input boundaries validate correctly; exceptions generated throw a standardized error envelope as previously handled by the existing API routers.
• Used correlation ID propagation correctly without modifying existing AsyncLocalStorage behavior.
