Polish UI consistency across all CRUD forms and fix data display issues

- Rewrite ResidenceFormView to use standard Form/Section pattern matching TaskFormView
- Remove unused organic form components (OrganicFormSection, OrganicFormTextField, etc.)
- Fix DocumentFormView: NavigationView→NavigationStack, WarmGradientBackground→appBackgroundPrimary, listRowBackground→sectionBackground
- Add Required footer to residence name field and task title/property fields
- Remove redundant Required footers from pickers that always have values
- Fix grey priority dots on kanban cards by guarding PriorityBadge in DynamicTaskCard and TaskCard
- Fix empty frequency labels showing on task cards
- Fix contractor Maps URL building to filter empty strings
