ui: Project dropdown in new task dialog, first field, defaults to /workspace/claudomator

- Moved working directory to first field, renamed to "Project"
- Replaced text input with a select populated from GET /api/workspaces
  (lists subdirs of /workspace dynamically)
- "Create new project…" option reveals a custom path input
- elaborate result handler sets select or falls back to new-project input
- Added GET /api/workspaces endpoint in server.go
