chore(deps): upgrade Angular 18 → 19

- ng update @angular/core@19 @angular/cli@19 @angular/material@19 @angular-eslint/schematics@19
- Migration: remove standalone:true (now default in v19) from 60 components
- Migration: zone.js 0.14 → 0.15
- Fix pre-existing build budget error: raise initial bundle limit to 5mb (app ships large static JSON assets)
