feat: add session name input to tool starter

ToolStarter (used by FAB and workspace detail):
- Add Session Name text input, defaulting to workspace.name
- Pass user-provided name to createInstance display_name parameter
- If left empty or only whitespace, falls back to auto-generated name

Quality gates: tsc --noEmit pass, npm run build pass, 82/82 tests pass
