Extend date range to support pre-2000 dates

[Majorfi]

Summary

Extends the calendar date picker's supported range to include dates before 2000, enabling filtering of historical photos and events from earlier decades.

What changed

• Updated startMonth parameter in the Calendar component from a more recent start year to 1900 in DateRangeFilterGroup.tsx, enabling users to select dates spanning back to the 1900s

Risks

• Rendering performance may be affected when users navigate through centuries of calendar months (though the UI uses dropdown navigation to mitigate this)
• Edge cases with very old dates and timezone handling should be verified across different browsers

Test plan

1. Open the date range filter and verify the calendar allows navigation back to years in the 1900s
2. Select a date from the 1900s and confirm it's correctly applied as a filter
3. Test year dropdown navigation to ensure smooth performance when jumping between distant years
4. Verify dates are formatted and displayed correctly in the UI for pre-2000 dates

Docs impact

Update any user documentation or release notes that mention the supported date range if applicable
