feat: replace global year selector with per-page date range filters (Story 17.12)

[daveharmswebdev]

Summary

• Replace global YearSelectorService + YearSelectorComponent with per-page DateRangeFilterComponent instances on Dashboard, Properties list, and Property detail
• Add dateFrom/dateTo query params to 3 backend endpoints (GetAllProperties, GetPropertyById, GetDashboardTotals) with backward-compatible year fallback
• Add last-year preset to DateRangeFilterComponent and DateRangePreset type
• Decouple Income component and Report dialogs from removed global year state
• Delete YearSelectorService, YearSelectorComponent, and all related files (−913 lines)
• Dynamic stat labels on Property detail ("YTD Expenses" vs "Expenses" based on preset)

Acceptance Criteria

• AC-1: Year selector removed from sidebar
• AC-2: Dashboard date range filter with presets (default: This Year)
• AC-3: Property detail date range filter with dynamic labels
• AC-4: Properties list date range filter (default: This Year)
• AC-5: Income list decoupled from global year
• AC-6: Report dialogs unaffected (own year selector, defaults to current year)
• AC-7: Full cleanup — no remaining references to removed components

Test plan

• All 2583 frontend unit tests pass
• All 1535 backend unit tests pass
• Manual smoke: Dashboard loads with "This Year" default, changing filter updates totals
• Manual smoke: Properties list loads with date range filter
• Manual smoke: Property detail shows date range filter, stat cards update, labels change
• Manual smoke: Income list works without global year interference
• Manual smoke: Batch report dialog opens, defaults to current year
• Manual smoke: Sidebar has no year selector on desktop, tablet, and mobile
