Add Contract Initialization State Validation

��# Issue 17: Add Contract Initialization State Validation

Problem

initialize doesn't verify all storage is in consistent state. Edge case: partial init could leave contract broken.

Solution

• Add verify_initialized() helper to check all required fields are set
• Call verification at start of all write operations
• Return NotInitialized error if state is inconsistent
• Prevents writes to uninitialized or corrupted contracts

Implementation Tasks

• Implement verify_initialized() helper function
• Check: Admin exists, all critical storage initialized
• Add call to verify_initialized() in record_ballot, record_token, etc.
• Return Err(ContractError::NotInitialized) if check fails
• Unit tests: contract valid after initialization
• Unit tests: write operations fail on uninitialized contract

Note for Contributors

This is a reliability guard to prevent partial initialization corruption. The verify function should check that the Admin key exists and is not zero address, and that all required storage slots are in a consistent state. Call verify at the start of every write operation before performing any state changes. This is defensive programming � in normal operation, contracts will always be initialized, but this guard catches edge cases and corrupted states. If verification fails, return NotInitialized error and log the inconsistency. Consider implementing a full storage consistency check (not just Admin presence). Initialize all critical fields together in the initialize function to maintain consistency.

Good day maintainer..

I’m a full-stack and test integration developer…. 

Please assign this task to me…

Hello team,
I'd like to take on this task and feel free to assign it to me.
Looking forward to getting started!

Hi maintainer, I'd like to take this on. I can add a centralized initialization verification helper, apply it consistently across write operations, and extend the error handling and test coverage to ensure uninitialized or inconsistent contract states are detected early and cannot be modified.Please assign me

Good day!!
I would like to work on this issue.

I have experience with Rust smart contracts, state validation, error handling, and defensive programming. I can implement a robust "verify_initialized()" helper that validates critical contract state, ensures required storage entries exist, and prevents write operations from executing when the contract is uninitialized or inconsistent.

My approach will include integrating initialization checks into all write paths, introducing proper "NotInitialized" error handling, adding consistency validation for critical storage fields, and creating comprehensive tests covering successful initialization, corrupted state scenarios, and write-operation protection.

Thank you
