chore(deps): upgrade Angular 19 → 20

- ng update @angular/core@20 @angular/cli@20 @angular/material@20 @angular-eslint@20 @angular/google-maps@20
- Remove ng-chartist (abandoned, incompatible with Angular 20): replace <x-chartist> with <app-bars-chart> in dropzones-bar and jumps-by-month
- Migrate all constructor injection to inject() function (ng generate @angular/core:inject, 67 files)
- TypeScript 5.5 → 5.9.3
- DOCUMENT import moved from @angular/common to @angular/core (automatic migration)
- tsconfig moduleResolution updated to "bundler"
