Turn on x/group_vesting (testnet, 1 % test)

Turns vesting on. Only Global may fund schedules. Sets the owner wallet for the stolen-key path. Two sell-cap groups: team (2 % of allocation per 90 days, first year after the cliff, then the held part opens over two equal stages) and investors (1.5 % of supply per 90 days, shared). Testnet runs a 1 % copy with time divided by 30; real lock at mainnet.
