refactor(common): align hardhat task arguments and definitions

[isaacdecoded]

Closes https://github.com/zama-ai/fhevm-internal/issues/395

[zmalatrax]

host-contracts/tasks/taskUtils.ts still uses fs.readFileSync + dotenv.parse

File: host-contracts/tasks/taskUtils.ts:40,62

This file still has the old pattern with customKmsVerifierAddress / customInputVerifierAddress params and dotenv.parse(fs.readFileSync('addresses/.env.host')).

[zmalatrax]

gateway-contracts/tasks/reshareKeys.ts still uses inline dotenv.config

File: gateway-contracts/tasks/reshareKeys.ts:23,49

Two tasks (task:prssInit, task:keyReshareSameSet) already use useInternalProxyAddress and getRequiredEnvVar but call dotenv.config({ path: path.join(ADDRESSES_DIR, ".env.gateway"), override: true }) directly instead of using loadGatewayAddresses().

Since the gateway utils already have that helper, these should use it for consistency.
