📔 Objective

This PR updates the app to use AGP v9.0.0 and Hilt v2.59.

This is a major update to AGP and this PR addresses several changes required to make it all work but there is still some amount of deprecated code that is still in use after this PR is done (baby steps).

• Removed the Kotlin Android Plugin
• Updated to Hilt v2.59.1 (Requires AGP 9)
• Updated gralde.properties to use new default and disable new defaults we are not yet ready for.
  • android.newDsl is currently set to false, this is the biggest one that still requires a lot of work to update.

⏰ Reminders before review

• Contributor guidelines followed
• All formatters and local linters executed and passed
• Written new unit and / or integration tests where applicable
• Protected functional changes with optionality (feature flags)
• Used internationalization (i18n) for all UI strings
• CI builds passed
• Communicated to DevOps any deployment requirements
• Updated any necessary documentation (Confluence, contributing docs) or informed the documentation team
