Fix babysit logging, achievement table name, and blacksmith repair costs

- runAutoBabysitDay now logs daily totals (was silently skipping logBabysitActivity)
- Stop wiping babysit_log on expiry/cancel; clear at next purchase instead so history persists between services
- Fix achievement query referencing wrong table name (babysit_log -> adventure_babysit_log)
- Tune blacksmith baseRates ([1,3,8,20,55,150] -> [1,2,5,12,30,80]) and soften the convexity (damage/100 -> damage/200) so mid-game repair drag isn't punitive
