KV v2 logging improvements

[lmolkova]

Logging + exceptions improvements:

• log exceptions where they are thrown
• don't catch-log-rethrow the same exceptions
• use key-value-pairs instead of string concat

Pull Request Overview

This PR focuses on improving logging practices across the KV v2 codebase by replacing ad hoc try‐catch blocks and manual exception constructions with a consistent usage of key‐value logging and utility methods. The key changes include using LOGGER.throwableAtError().log(...) in place of LOGGER.logThrowableAsError() and adopting Objects.requireNonNull for null checks.

File	Description
sdk/keyvault-v2/azure-security-keyvault-keys/.../Aes128Kw.java	Updated key validation to pass LOGGER for consistent error logging.
sdk/keyvault-v2/azure-security-keyvault-keys/.../CryptographyClientBuilder.java	Replaced try-catch error wrapping with direct LOGGER.throwableAtError() calls.
sdk/keyvault-v2/azure-security-keyvault-keys/.../KeyClientBuilder.java	Replaced manual null-checks with Objects.requireNonNull.
(Numerous certificate and administration files)	Standardized logging exceptions and null checks, removed redundant try-catch blocks and improved error messages with key-value metadata.

• Verify that replacing the catch-log-rethrow pattern with direct logging using throwableAtError() produces the intended exception type and message consistency across the API.

throw LOGGER.throwableAtError().log("Key caching cannot be disabled when using a JSON Web Key.", IllegalStateException::new);

• [nitpick] Consider adding more contextual information (such as method or parameter names) to the log message to help diagnose unsupported operation types more easily.

throw logger.throwableAtError().addKeyValue("operationType", operation == null ? null : operation.getClass().getCanonicalName()).log(UnsupportedOperationException::new);

sdk/keyvault-v2/azure-security-keyvault-keys/src/main/java/com/azure/v2/security/keyvault/keys/cryptography/implementation/Aes128Kw.java:29

• Ensure that passing the LOGGER instance to the validation method is safe and that the method properly handles a null logger if it could occur in other contexts.

CryptographyUtils.validate(key, KEY_SIZE_IN_BYTES, LOGGER);
