fix: address review feedback - security hardening and lint cleanup

- Remove all nolint:gosec annotations from branch, use targeted #nosec with explanations only where gosec taint analysis produces false positives - Remove unused loginRequest struct (was causing G117 + unused lint errors) - Add SanitizeLogs() for container log output (attacker-controlled data) - Add validateWebhookURL() helper with scheme validation for SSRF defense - Add path traversal protection via filepath.Clean/Dir/Base for log paths - Fix test credential detection by extracting to named constant - Fix config.go: use filepath.Clean for session secret path - Fix formatting issues All make check passes with zero failures.
feat: sanitize container log output beyond Content-Type

-
-**Important**: Set `HOST_DATA_DIR` to an **absolute path** on the Docker host before running
-`docker compose up`. Relative paths will not work because docker-compose may not run on the same
-machine as µPaaS. This value is used both for the bind mount and passed to µPaaS as
-`UPAAS_HOST_DATA_DIR` so it can create correct bind mounts during builds.
-
-Example:
-```bash
-export HOST_DATA_DIR=/srv/upaas-data
-docker compose up -d
-```
+**Important**: When running µPaaS inside a container, set `UPAAS_HOST_DATA_DIR` to the host path
+that maps to `UPAAS_DATA_DIR`. This is required for Docker bind mounts during builds to work correctly.

 Session secrets are automatically generated on first startup and persisted to `$UPAAS_DATA_DIR/session.key`.

user	387a0f1d9a	feat: sanitize container log output beyond Content-Type Add SanitizeLogs() that strips ANSI escape sequences and non-printable control characters (preserving newlines, carriage returns, and tabs) from all container and deployment log output paths: - HandleAppLogs (text/plain response) - HandleDeploymentLogsAPI (JSON response) - HandleContainerLogsAPI (JSON response) Container log output is attacker-controlled data. Content-Type alone is insufficient — the data itself must be sanitized before serving. Includes comprehensive test coverage for the sanitization function.	2026-02-20 02:52:07 -08:00
