Add bonus actions, coupons, and passcodes

Open Post-entry → Actions, choose an action, set instructions, entry value, and frequency, then preview it.

Coupon actions distribute an available code after the required event. Passcode actions validate or consume an imported code according to configuration. Import code files, review counts and failures, and protect real codes from screenshots or public exports.

Test completed, repeated, invalid, exhausted, and unavailable states. Explain exactly what the action does and never describe an external social action as verified when Revup cannot verify it.
