refactor: standardize notify helper usage and document migration workflow

- Refactor notify usage in GiftedDialog.vue, AccountViewView.vue, ClaimView.vue, and DataExportSection.vue:
  • Use notify as a property initialized in created() with createNotifyHelpers(this.$notify)
  • Remove getter-based notify patterns for consistency and lifecycle safety
  • Fix linter/type errors related to notify property initialization

- Add mandatory per-file migration workflow to doc/migration-progress-tracker.md:
  • For each file: (1) migrate to PlatformServiceMixin, (2) immediately standardize notify usage and fix linter/type errors
  • Clarifies this two-step process is required for every file, not as a global sweep

All migrated files are now consistent, maintainable, and ready for further migration work.

 # Migration Progress Tracker: PlatformServiceMixin & 52-File Migration
 
+## Per-File Migration Workflow (MANDATORY)
+
+For each file migrated:
+1. **First**, migrate to PlatformServiceMixin (replace all databaseUtil usage, etc.).
+2. **Immediately after**, standardize notify helper usage (property + created() pattern) and fix any related linter/type errors.
+
+**This two-step process is to be followed for every file, not as a global sweep at the end.**
+
+Anyone picking up this migration should follow this workflow for consistency and completeness.
