Complete ProjectsView.vue Triple Migration Pattern with literal extraction

Apply full database migration (databaseUtil → PlatformServiceMixin), replace
raw SQL with service methods, migrate 3 notifications to helper methods.
Preserve 1 complex modal for advanced routing features while extracting
all literal strings to NOTIFY_CAMERA_SHARE_METHOD constant.

Add computed properties (offerTabClasses, projectTabClasses) to streamline
template logic and comprehensive JSDoc documentation for all methods.
Update migration templates to mandate literal extraction from complex modals.

ProjectsView.vue now appropriately incomplete: helper methods for simple
notifications, raw $notify preserved only where advanced features required.
