feat: custom date range filter on calendar page

Browse Source 
- Backend: /api/eco/calendar accepts date_from + date_to query params
  when period=custom; get_calendar() uses them directly without override
  Limit raised to 5000 for wide date ranges
- Frontend: "Custom" tab at end of period list; shows two date inputs
  (from/to) with Apply button; displays day count; fetches on Apply click
  (not on every keystroke to avoid hammering the API)
