ci: fix linter errors in CI pipeline

- Fixed `musttag` errors in `web/backend/api/config.go` by explicitly decoding JSON into an anonymous struct.
- Fixed a `govet` shadow error in `pkg/providers/common/http_logger.go`.
- Fixed formatting errors reported by `golines` and `gci` in `pkg/config/config.go`, `pkg/config/security.go`, and `pkg/providers/anthropic_messages/provider.go`.
