Hardcode inflation period start blocks

[bobo-k2]

Pull Request Summary

Initially I used Blockscout API to determine starting block of inflation period 1. Since Subscan started to give us "too many requests" error I decided to hardcode block number for each network since this will never change. I should do that intially.

Also reordered latest promotion card to be visible on dApp staking page

Thanks, nice catch. The value is 0, but there was error in showing the value. Fixed in https://github.com/AstarNetwork/astar-apps/pull/1300/commits/b429ce3e2a84d5c7f33ece941340af1cf06a1cac
