This commit completes the "Improving Structure & Maintainability" phase by fundamentally refactoring the frontend architecture.
- Introduced a central state store (store.js) to act as a single source of truth, eliminating global variables and making data flow predictable through an event-based system.
- Replaced innerHTML with component-based rendering for all major UI elements, including warranty cards, tags, and all modals (Edit, Delete, Claims, Notes, Paperless). This improves security, performance, and maintainability.
- Created reusable UI component modules (warrantyCard.js, editModal.js, claims.js, etc.) and used an HTML <template> for the main warranty card to separate markup from logic.
