Security Hardening and GraphQL Caching (#69)

* feat: add security middleware, graphql apq, and improved linting

- Add RateLimit, RequestValidation, and CORS middleware.
- Configure middleware chain in API server.
- Implement Redis cache for GraphQL Automatic Persisted Queries.
- Add .golangci.yml and fix linting issues (shadowing, timeouts).

* feat: security, caching and linting config

- Fix .golangci.yml config for govet shadow check
- (Previous changes: Security middleware, GraphQL APQ, Linting fixes)

* fix: resolve remaining lint errors

- Fix unhandled errors in tests (errcheck)
- Define constants for repeated strings (goconst)
- Suppress high complexity warnings with nolint:gocyclo
- Fix integer overflow warnings (gosec)
- Add package comments
- Split long lines (lll)
- Rename Analyse -> Analyze (misspell)
- Fix naked returns and unused params
