style: fix all ruff and eslint errors across codebase

Backend (ruff):
- Fix 106 errors: move imports to top of file (E402)
- Remove unused imports (F401)
- Add missing imports for undefined names (F821)
- Remove unused variables (F841)
- Fix test_models.py broken RefreshToken test
- Fix test_projects_api.py missing TestClient import

Frontend (eslint):
- Remove unused imports/variables across 10 files
- Fix explicit any types in client.ts and sessions.ts
- Clean up empty block statements in terminal.tsx

Quality gates: ruff (pass), eslint (pass), tsc --noEmit (pass),
pytest (98 passed, 4 pre-existing failures)

+# Tool Images
+
+This directory contains Dockerfile templates for the base tool types used in Headquarter.
+
+## Available Images
+
+| File | Tool | Description |
+|------|------|-------------|
+| `base.dockerfile` | - | Common base with git, nvim, ranger, tmux, node |
+| `code-server.dockerfile` | VS Code | Browser-based VS Code with extra tools |
+| `jupyter.dockerfile` | Jupyter | Jupyter Lab/Notebook with extra tools |
+| `opencode.dockerfile` | OpenCode | OpenCode agent server |
+| `pi-agent.dockerfile` | Pi Agent | Pi coding agent with full terminal setup |
+
+## Usage
+
+When creating a tool type in the Tool Workshop, you can reference these Dockerfiles:
+
+1. Copy the contents of the desired `.dockerfile`
+2. Paste into the "Dockerfile Template" field
+3. Set `definition_type` to `dockerfile`
+
+## Building Locally
+
+To test an image locally:
+
+```bash
+cd tool-images
+docker build -f pi-agent.dockerfile -t pi-agent:latest .
+docker run -it pi-agent:latest
+```
+
+## Customizing
+
+All images include:
+- **git** - Version control
+- **neovim** - Terminal editor
+- **ranger** - Terminal file manager
+- **tmux** - Terminal multiplexer
+- **htop** - Process viewer
+- **tree** - Directory tree
+- **jq** - JSON processor
+- **Node.js 20** - For npm-based tools
+
+The `pi-agent` image additionally includes the [Pi Coding Agent](https://pi.dev/) for AI-assisted development.
+
+## Adding New Images
+
+1. Create a new `.dockerfile` in this directory
+2. Use `base.dockerfile` as a starting point if applicable
+3. Document it in the table above
+4. Update the tool type in the database via the Tool Workshop
