Fix: Add missing Handlebars partials to preload function

- Added partial-active-effects.hbs and partial-item-effects.hbs to preloadHandlebarsTemplates()
- These partials were used in sheets but not preloaded, causing render errors
- Fixed lang/fr.json formatting (added closing brace and newline)
- Added test script to validate template loading
- Added CORRECTIONS.md documentation
