feat: block gas limit should be 30_000_000

[natanasow]

Description:

When querying block information, the block gasLimit is shown as 15M GAS (15000000). The correct value should be 30M GAS (30000000). This happens for all public networks (mainnet, testnet and previewnet).

Related issue(s):

Fixes #2740

Notes for reviewer:

We were using max gas per sec as a block limit gas which is incorrect. In the hedera ecosystem, there is a limit of up to 15 000 000 gas per sec (here) which means that a single transaction could use max 15 000 000 as a gas limit. Meanwhile one "block" is generated every 2 seconds which means that max block gas is 30 0000 000 = 15 000 000 per sec * 2 sec.
