apply isVerified property for a list of SC's

[cfaur09]

Reasoning

• To enhance performance by reducing the number of verification requests for smart contracts and to display SC's that are code verified

Proposed Changes

• Implemented a new method getVerifiedAccounts in the account service to fetch a list of verified smart contract addresses.
• Added a new job in CacheWarmerService to periodically update and cache the list of verified smart contracts.
• Modified getAccountsRaw method to check against the cached list of verified smart contracts and conditionally set the isVerified property for relevant accounts.

How to test (DEVNET)

• /accounts?isSmartContract=true&size=400 -> should return for some SC's isVerified property. Otherwise, isVerified property is not defined
• /accounts?size=10000 -> should return also for some SC's isVerified property
