fix(templates): complete revision of actor templates to remove duplicates and fix inconsistencies

- Fixed grid-2 to grid-2col CSS class usage
- Replaced improper <p><a> tags with <div><a> in item lists (actor-weapons, actor-defenses, group-items, group-vehicles)
- Fixed typos: smarttlk -> smarttl, compétence -> Compétence
- Fixed duplicate class attributes
- Standardized HTML comments to Handlebars comments ({{!-- --}})
- Added missing localizations for Character and Skills headers
- Removed orphan {{/if}} tag in character-id.hbs
- Created npc-skill-category.hbs partial to eliminate 150+ lines of duplicated skill category code in actor-npc-sheet.hbs
- Created item-list.hbs partial for reusable item list display
- Fixed html.find(...).forEach error in roll.mjs by ensuring jQuery object
- Added .history/ to .gitignore
