fix: make admin user deletion atomic and surface errors in UI

deleteUser() ran each child-table cleanup as a separate statement, so a foreign-key violation on any step (e.g. sync_log rows from other users referencing the deleted user's notes) would abort mid-way and leave the database in a partial state. The API swallowed the error and the admin page silently ignored the non-ok response, so clicking Delete and confirming appeared to do nothing. - Wrap the full cascade in a single sqlite transaction so the deletion is atomic. - Also remove rows in sync_log, note_user_state, note_collaborators, note_versions, and attachments that belong to other users but reference the deleted user's notes, so the final DELETE FROM notes cannot trip a foreign-key check. - Surface delete failures in the users settings UI instead of silently swallowing them. - Add data-testids on the user row and delete button to support tests. - Add e2e coverage for the admin user deletion flow (happy path, cancelled confirmation, and a user with notes / tags / attachments / preferences / api keys). https://claude.ai/code/session_015T2HE6VzB64ZmSSyy1Wz4R
