fix: resolve Angular strictTemplates errors with proper TypeScript typing

Summary

This PR resolves all Angular strictTemplates: true compilation errors that were preventing the application from building. The changes involve systematic TypeScript type improvements across multiple components, with a focus on proper type annotations, form control typing, and template property access.

Key Changes:

• Fixed property access on unknown types using proper type casting and interface definitions
• Updated form control typing from any[] to proper interfaces (JobType, AppointmentType, EngineerDoc)
• Converted patches component to use Observable pattern for consistency with child components
• Fixed boolean attribute binding in template forms
• Resolved CDK drag-and-drop and directive input type mismatches

Review & Testing Checklist for Human

🔴 High Priority (3 items):

• Test patches management functionality thoroughly - The allPatches property was converted from PatchModel[] to Observable<PatchModel[]> using BehaviorSubject. Verify patch creation, editing, deletion, and drag-and-drop still work correctly.
• Verify engineer selection and listing workflows - Changed User type to EngineerDoc type in engineer selection. Test engineer filtering, selection, and assignment processes.
• Test form submissions and validation - Form control types were updated across multiple components. Verify appointment booking, debt editing, and contractual forms still validate and submit correctly.

Recommended Test Plan:

1. Navigate to Today Filters and test job type/appointment type filtering
2. Go to Engineers section and test engineer selection and qualification display
3. Test Patches functionality (create, edit, delete, drag-and-drop)
4. Test appointment booking and form validation
5. Verify capacity template downloads work correctly

Notes

• Type Safety Approach: Used $any() casting in templates where complex nested property access was causing strictTemplates errors. While this resolves compilation issues, these locations should be monitored for potential runtime errors.
• Observable Pattern: The patches component now follows the same Observable pattern as its child components, improving architectural consistency.
• Backward Compatibility: All changes maintain existing API contracts while adding proper TypeScript typing.
