- connections.py: Update Google Drive OAuth to broader `drive` scope (D-17)
instead of `drive.file` so authorized users can operate on all existing Drive
items, not just files created by this app. Both initiation and callback flows
updated to keep scopes consistent.
- schemas.py: Add Phase 13 typed response schemas — ConnectionHealthOut, ReconnectOut,
ContentResultOut, MutationResultOut, and request schemas CreateFolderRequest,
RenameItemRequest, MoveItemRequest. All credential-free (T-13-14, CONN-03).
- api/cloud.js: Add centralized frontend helpers for getConnectionHealth,
reconnectCloudConnection, testCloudConnection (D-12, D-13), plus authorized
cloud content and mutation helpers: openCloudFile, previewCloudFile,
createCloudFolder, renameCloudItem, moveCloudItem, deleteCloudItem, uploadCloudFile.
All reconnect/health/test tests pass (14/14). Security suite passes (19/19).
