Fixed password settings so that changed passwords actually work and I can actually change the passwords

 10. **Task Editing:** Implemented inline editing for task descriptions using an active text box state with "Save/Cancel" actions.
 11. **UI Cleanup:** Removed hardcoded, prototype placeholder notes from the `TaskDetail` modal to prepare for future dynamic notes integration.
 12. **Permanent Deletion:** Added a "Delete task permanently" button to the `TaskDetail` sidebar with a confirmation dialog, backed by a new `DELETE /tasks/{id}` API endpoint.
+13. **Permanent Deletion Wiring Fix:** Resolved a three-layer bug where the delete button was non-functional:
+    - Added the missing `onDeleteTask` prop to the `TaskDetail` component signature in `screens.jsx`.
+    - Added the missing `deleteTask` handler in `app.jsx` (calls `api.deleteTask`, writes an audit entry, and closes the modal).
+    - Restarted the FastAPI backend so the previously-added `DELETE /tasks/{id}` route was loaded into the running process (was returning 405 prior to restart).
+14. **Password Management:** Made the "Change password" flow real (previously a placeholder UI).
+    - **Backend:** Added `PasswordChange` schema and a new `POST /users/{user_id}/password` endpoint that verifies the current password (401 on mismatch) before re-hashing and saving the new one.
+    - **API client:** Added `api.changePassword(id, oldPwd, newPwd)` that surfaces the backend's `detail` message inline rather than just the HTTP status text.
+    - **Frontend:** Wired the previously-inert "Update password" button in `SettingsScreen` — submits via `onChangePassword`, shows inline error / success states, disables while in flight, clears the fields on success, and writes a `password_changed` audit entry.
+    - **Defaults confirmed:** Seeded users (`seed.py`) and admin-created users (`app.jsx`) both default to `password123`.
+15. **Real Login Authentication:** Fixed a security bug where the login screen accepted any password.
+    - The password input on `LoginScreen` was a decorative `defaultValue` field — the button submitted with no password, and `onLogin` had a fallback default of `"password123"` which matched every seeded account.
+    - Bound the input to component state, send the actual typed password to `api.login`, and let backend `401`s propagate so the screen can render an inline "Incorrect password" message instead of silently letting anyone in.
+    - Enter key now submits, and the button disables while the request is in flight.
 
 ### Phase 3: Advanced Features
 - **Real-time Notifications:** Explore WebSockets for task assignments.
