Add symbol size migration: update outdated defaults on load

Browse Source 
When loading saved state, symbols with known outdated default sizes
(e.g., photoeye 56x20) are migrated to current defaults (30x14).
Only exact matches of old defaults are migrated — user-resized
symbols keep their custom dimensions.
