Aliasing table reference in cost_per_query and hourly_spend models

[saurasingh]

@NiallRees For the two models in the subject, we need to alias tables like daily_rates, 'stg_usage_in_currency_daily', stg_metering_history, stg_serverless_task_history, and stg_metering_daily_history. As the dbt CI adds the schema name as the prefix to the table name. Referencing columns from these tables breaks the object definition as they defer in the names, having an alias name should fix this.

Please refer to the screenshots:

Tried creating PR to fix this by myself but was not able to commit changes.
