Kyle Isom ec7c966ad2 trusted proxy, TOTP replay protection, new tests
- Trusted proxy config option for proxy-aware IP extraction
  used by rate limiting and audit logs; validates proxy IP
  before trusting X-Forwarded-For / X-Real-IP headers
- TOTP replay protection via counter-based validation to
  reject reused codes within the same time step (±30s)
- RateLimit middleware updated to extract client IP from
  proxy headers without IP spoofing risk
- New tests for ClientIP proxy logic (spoofed headers,
  fallback) and extended rate-limit proxy coverage
- HTMX error banner script integrated into web UI base
- .gitignore updated for mciasdb build artifact

Security: resolves CRIT-01 (TOTP replay attack) and
DEF-03 (proxy-unaware rate limiting); gRPC TOTP
enrollment aligned with REST via StorePendingTOTP

// mcias.js — HTMX event wiring for the MCIAS web UI.
// Show server error responses in the global #htmx-error-banner.
//
// HTMX 2.x fires htmx:responseError for 4xx/5xx responses and does not swap
// the body into the target by default. The server's renderError() always
// returns a <div class="alert alert-error"> fragment whose message is
// HTML-escaped server-side, so setting innerHTML here is safe.

var banner = document.getElementById('htmx-error-banner');

banner.innerHTML = body;
banner.style.display = '';

// Clear the error banner whenever a successful HTMX swap completes so
// stale errors do not persist after the user corrects their input.
