refactor: remove Tool Configs and Config Folders
These features are fully superseded by Config Profiles which provide:
- Env vars, file mounts, port overrides, start commands, working dirs
- Git mounts, profile composition, cycle detection
- Default selection, project/tool-type scoping
Changes:
- Delete backend models: ToolConfig, ConfigFolder
- Delete backend APIs: tool_configs.py, config_folders.py
- Delete frontend API clients: tool_configs.ts, config_folders.ts
- Remove Tool Config fetching from start_instance, use ConfigProfile only
- Simplify merge_with_config to accept only profile (no tool_configs)
- Remove configs/folders tabs from Tool Workshop page
- Delete associated integration and unit tests
- Add Alembic migration to drop tool_configs and config_folders tables
Quality gates: backend tests 59 passed, frontend typecheck clean
