Remove "Auto-Contribute" from Rewards Summary for Japan region

[LaurenWags]

Description

Rewards panel UI is being refreshed with #14602

Previously line items only displayed on the summary as they occurred. However, with the UI refresh the line items are always there. In the case of Japan region, Auto Contribute is not applicable, so AC should be removed from the summary.

Steps to Reproduce

1. Install 1.31.x with Japan region, staging env
2. Enable Rewards
3. Look at summary (in my example I have bF wallet connected, but AC should be removed regardless of whether bF wallet is connected or not)

Repeat for Upgrade case also

Actual result:

Auto Contribute is listed in summary but is not applicable to Japan region:

Expected result:

AC should not be listed in summary for Japan region

Based on discussions, @zenparsing's solution will be as follows: If Auto-Contribute is disabled, then the line item will disappear from the summary. Since it is always disabled in JP region for now, it will not appear. (If US user has it disabled, it will also not appear.)
