Gate sheets tools behind ENABLE_SHEETS_TOOLS env flag

Sheets tools were always registered in HTTP mode and removed in stdio.
Now they're opt-in via `enable_sheets_tools` (default False), so HTTP
deployments without Google OAuth configured don't expose them either.
Also strips `output_spreadsheet_title` from the HTTP results schema
when sheets are disabled.
