Text box for the Meta Data Purge Interval settings in the Auto-Compaction settings tab is not of the type number

The text box provided in the Meta Data Purge Interval settings in the Auto-Compaction settings tab is not of the type = number. While we show error message to the user if they enter a non-number character, it's not consistent with the page, where all other input types are number, where non-numerical characters are not taken as input. Also the user experience is degraded. Would be good to include the type=number in the input and include the min and max properties too to specify the range.
