feat(governance): activate OpenGov production periods and add Welati tracks

Upgrade all 15 OpenGov track periods from Westend test values (minutes)
to Polkadot production values (hours/days). Add 3 new Welati governance
tracks (welati_election, welati_admin, citizenship_admin) with origins
and XCM routing for RC → People Chain governance via OpenGov referenda.

Bump spec_version: 1_020_007 → 1_020_008
