docs(3d): restore FAS3 audit doc from cb49301 + add 3d semantics
- Restore full docs/FAS3-COOKING-SESSIONS-AUDIT.md from cb49301
(hermetic test rules, REUSE/GAP matrix, anti-duplication rationale,
step plans 3a-3d). Append section 7 with 3d merge/undo semantics.
- Update 7.6 wrapper reference to c1ab2c8 behaviour.
- Fix migration 0017: cast completed_at/started_at/created_at to UTC
before extracting DATE. Idempotent (WHERE meal_date IS NULL); already
backfilled rows unaffected. Runner does not checksum files.
- Clarify meal_date purpose: future UTC statistics/queries; undo uses
stored mealBoxMutations.
