feat(routes): unify won leads and projects on a single /projects/:id page

- add role-prefix-free /projects/:id route (OWNER/ADMIN/FIELD_AGENT; ABAC guard lands in Phase 8)
- relax detail lookup so admin/field-agent open any project, owners only their own
- kanban drawer + project list route won leads (with projectId) to /projects/:id; pre-sale leads stay on the lead page
