feat: Phase 1 — remove bug feature and dead code

- Delete Bug struct, BugToAtom, SourceBug, TypeBug, TypeNote
- Remove bug store methods (SaveBug, GetBugs, ResolveBug, etc.)
- Remove HandleGetBugs, HandleReportBug, bug branches in handlers
- Remove bug routes, bugs.html template, bug UI from index.html
- Remove AddMealToPlanner stub + interface method
- Migration 018: DROP TABLE IF EXISTS bugs
