[UPGRADE] Ionic 6 → 8 migration

[BAWES]

Overview

Upgrade Ionic from v6 to v8. Can be done after Angular is on v19 (issue #28).

Prerequisites

• Issue [UPGRADE] Angular 18 → 19 + standalone schematic + new control flow #28 (Angular 18→19) must be merged first

Scope

1. Package update

npm install @ionic/angular@8 @ionic/angular-toolkit@9

2. Dark mode CSS migration

• Ionic 8 uses CSS import for dark mode instead of @media (prefers-color-scheme: dark)
• Audit src/global.scss and src/theme/variables.scss for all dark mode overrides
• Migrate to the new approach:

// OLD (remove this)
@media (prefers-color-scheme: dark) { ... }

// NEW
@import "@ionic/angular/css/palettes/dark.system.css";

3. Component API changes

• Review all ion-picker usages for API changes
• Review all ion-modal breakpoints usages
• Check IonRouterOutlet animation changes
• Remove any workarounds for Ionic 6 bugs that are now resolved

4. CSS variable audit

• Ionic 8 refreshed iOS design tokens
• Test all custom ion- component overrides in global.scss visually

Acceptance Criteria

• ng build completes without errors
• App renders correctly on iOS viewport
• App renders correctly on Android viewport
• Dark mode works correctly
• All modals open/close correctly
• Tab bar renders correctly
• All custom CSS overrides still apply as expected

Test Checklist

Manually test these critical pages after upgrade:

• Login page
• Candidate list
• Candidate view/form
• Company view
• Any page using ion-modal
• Any page using ion-picker or date selector
