Backport tips data refactor to previous arcs

MG changed stuff with tips in minagoroshi causing some things to be changed on our end, but it popped up an edge case that was pretty ugly. We fixed the edge case on minagoroshi (7ceaa8b4), but it would be good to reconcile a single tips data implementation to all arcs, which this refactored implementation should be able to cover.

The issue references a commit (7ceaa8b4) in the 'minagoroshi' arc that fixed an edge case with tips data. First, examine that commit to understand the refactored implementation. Then, identify the 'previous arcs' that need the changes. Look for files handling tips data across different arc directories. The goal is to apply a single, unified tips data implementation to all arcs, ensuring compatibility and no regressions.
