Estimator: Immich peak 3,290 -> 3,983 MB from the 4,000-photo import (R-1147, operator yes 2026-10-18); Immich alone on 8 GB now 'does not fit'

Rebuilt sizing-data.json; data cache-bust v5; SIZING.md table and the pinned test cases moved
with it. Before/after: audits/day-2026-10-18/P6-before-after.md.
