Description:

• This PR replaces all usages of the HbarLimit module with the new HbarLimitService class in the SdkClient and MetricService classes.
• Removes the HbarLimit module from the codebase.
• The addExpense logic in the new HbarLimitService has been updated to accept a nullable ethAddress value. Certain queries, such as getAccountInfo, getBalanceInfo, FileContentsQuery, etc., also add expenses to remainingBalance but don’t always require an originalCaller (ethAddress). Therefore, addExpense can now handle a nullable ethAddress value. If either ethAddress or ipAddress is valid, the spendingPlan logic is applied. Otherwise, it is skipped entirely.
• Moved the preemptive rate limit logic to the sdkClient.createFile() method.
• Related tests have been updated to align with the new HbarLimitService class.
• Updated log messages accordingly.
