Capacitor App Upgrade v7 to v8

Move a Capacitor 7 app to Capacitor 8 (current stable line: 8.5.x). Source of truth: https://capacitorjs.com/docs/updating/8-0

When to Use

• @capacitor/core in the snapshot below is 7.x and the user wants 8.x.
• After bumping to 8: content under the Android status/navigation bar (edge-to-edge), bridge_layout_main not found, Gradle "space-assignment syntax" deprecation warnings, Kotlin 2 kotlinOptions errors, or Geolocation timeouts.
• The user asks for the exact 7 -> 8 checklist.

Do not use:

• App on 6.x -> capacitor-app-upgrade-v6-to-v7 first. Multi-hop planning -> capacitor-app-upgrades.
• App already on 8.x -> capacitor-uiscene-migration (8.5 scene lifecycle), then capacitor-app-upgrade-v8-to-v9.
• Plugin library upgrade -> capacitor-plugin-upgrade-v7-to-v8.
• CocoaPods to SPM -> cocoapods-to-spm.
