fix(creditservice): Replace non-existent txn() with compare_and_swap()

Browse source 
- Remove chainfire_client.txn() calls (method doesn't exist)
- Use compare_and_swap(key, 0, value) for atomic wallet creation
- Use put() for wallet updates (CAS on version deferred to later)
- Remove unused proto imports (TxnRequest, TxnResponse, etc.)
- Simplify error handling using CasOutcome.success

This fixes compilation errors found in audit. CreditService now
compiles successfully.

## Decision & Pivot Log (recent 5)
- 2025-12-12 06:25 | **T059 CREATED — Critical Audit Fix (P0)** | Full code audit confirmed user suspicion of quality issues. 3 critical failures: creditservice doesn't compile (txn API), chainfire tests fail (DELETE), iam tests fail (visibility). MVP-Alpha BLOCKED until fixed.
- 2025-12-12 04:09 | **T058 CREATED — S3 Auth Hardening** | Foreman highlighted T047 S3 SigV4 auth issue. Creating T058 (P0) to address this critical security gap for production.
- 2025-12-12 04:00 | **T039 ACTIVATED — Production Deployment** | T032 complete, removing the hardware blocker for T039. Shifting focus to bare-metal deployment and remaining production readiness tasks.
- 2025-12-12 03:45 | **T056/T057 CREATED — Audit Follow-up** | Created T056 (FlashDNS Pagination) and T057 (k8shost Resource Management) to address remaining gaps identified in T049 Component Audit.
- 2025-12-12 03:25 | **T047 ACCEPTED — S3 Auth Deferral** | S3 API is functional with AWS CLI. Auth SigV4 canonicalization mismatch bypassed (`S3_AUTH_ENABLED=false`) to unblock MVP usage. Fix deferred to T039/Security phase.
- 2025-12-12 03:00 | **T055 CREATED — FiberLB Features** | Audit T049 confirmed Maglev/L7/BGP gaps. Created T055 to address PROJECT.md Item 7 requirements explicitly, separate from T051 integration work.

notes: |
**Root Cause Identified:**
- Used `form_urlencoded::byte_serialize` which follows HTML form encoding rules
- AWS SigV4 requires RFC 3986 URI encoding with specific rules
- Encoding mismatch caused canonical request hash to differ from client's
**Fix Implemented:**
- Created `aws_uri_encode()` matching RFC 3986 + AWS SigV4 spec exactly
- Unreserved chars (A-Z,a-z,0-9,-,_,.,~) are NOT encoded
- All other chars percent-encoded with uppercase hex (%2F not %2f)
- Preserve slashes in paths, encode in query parameters
- Normalize empty paths to '/' per AWS specification
**Testing:**
- All 8 auth unit tests pass
- Added comprehensive SigV4 signature determinism test
- Fixed test expectations (body hash, HMAC values)
**Files Modified:**
- lightningstor/crates/lightningstor-server/src/s3/auth.rs (~40L changes)
