Comprehensive security hardening from audit findings: - Add validation tags to all DTO request structs (max lengths, ranges, enums) - Replace unsafe type assertions with MustGetAuthUser helper across all handlers - Remove query-param token auth from admin middleware (prevents URL token leakage) - Add request validation calls in handlers that were missing c.Validate() - Remove goroutines in handlers (timezone update now synchronous) - Add sanitize middleware and path traversal protection (path_utils) - Stop resetting admin passwords on migration restart - Warn on well-known default SECRET_KEY - Add ~30 new test files covering security regressions, auth safety, repos, and services - Add deploy/ config, audit digests, and AUDIT_FINDINGS documentation Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
