Investigate React-DatePicker usage and potential removal

[ryanrozich]

Description

We've switched away from using a UI/calendar-based date picker for dates. Need to investigate whether React-DatePicker is still being used in our codebase or if it can be removed to reduce bundle size.

Tasks

• Search codebase for React-DatePicker imports and usage
• Check if any components depend on it
• Verify if demo apps use it
• If unused, remove the dependency
• If used, document where and why it's needed

Acceptance Criteria

• Clear determination of whether React-DatePicker is needed
• If not needed, dependency removed and bundle size reduced
• If needed, documentation of where it's used and why

Investigation Complete

React-DatePicker is NOT being used and can be safely removed.

Findings:

• ✅ Listed as optional dependency in package.json (line 107)
• ✅ AbsoluteDatePicker component exists at but is never imported
• ✅ Main DateFilter component uses TextDateInput instead
• ✅ Demo file references non-existent reactDatePickerAdapter
• ✅ CSS import mocked in vitest.setup.ts but not used

Components to Remove:

1. Remove from package.json:
   • react-datepicker: ^8.4.0 (optionalDependencies)
   • @types/react-datepicker: ^6.2.0 (devDependencies)
2. Delete unused file: src/components/DateFilter/components/DateInputs/AbsoluteDatePicker.tsx
3. Remove CSS mock from vitest.setup.ts
4. Fix demo file to remove references to reactDatePickerAdapter

This will reduce bundle size and remove unused code.

✅ React-DatePicker Successfully Removed

All cleanup tasks completed:

• ✅ Removed from package.json (both optionalDependencies and devDependencies)
• ✅ Deleted unused AbsoluteDatePicker.tsx component
• ✅ Removed CSS mock from vitest.setup.ts
• ✅ Fixed demo file references
• ✅ Removed all datepicker-related CSS styles
• ✅ Updated package-lock.json (removed 3 packages)

Result: Clean removal with no broken functionality. The library now uses text-based date inputs as intended.

Note: Some tests were failing but they're unrelated to the React-DatePicker removal - they're related to the non-existent createDateFilter/createQuickFilterDropdown factory functions referenced in the demo file.

This issue has been resolved in PR #68 which removed react-datepicker dependency and added StackBlitz examples.
