Add delegated value setter for authorized address

[Copilot]

Introduces a second privileged address (0xA9D1e08C7793af67e9d92fe308d5697FB81d3E43) with limited permissions to set contract value, while maintaining owner control over authorization.

Changes

• New state variable: authorizedAddress initialized to 0xA9D1e08C7793af67e9d92fe308d5697FB81d3E43
• Access control: onlyAuthorized modifier restricts delegated functions
• Delegated function: setValueAuthorized(uint256) allows authorized address to set contract value
• Owner management: setAuthorizedAddress(address) restricted to owner only (prevents self-modification by authorized address)
• Event: AuthorizedAddressUpdated emitted on authorization changes

Usage

// Authorized address can set value
contract.setValueAuthorized(100);  // from 0xA9D1e08C7793af67e9d92fe308d5697FB81d3E43

// Owner retains control over authorization
contract.setAuthorizedAddress(newAddress);  // from 0x0540e1dA908D032D2F74D50C06397cB5f2cbfDdB

Security: Authorized address cannot elevate privileges or modify its own authorization.
