refactor: drop unused DailyLoginBonuses table + importer

The captured shape ({"1":[], "3":[], "4":[]}) is the empty-period
wire echo; the client parser (LoadDetail.cs:553) only reads normal/total/
campaign. Table, entity, seed, and importer were never wired to a code path.

Replaced by config-section catalog + service in the follow-up commits.
