[Android] Setup sample lint and formatting

[kiftio]

What changes are you making?

Detekt and Android Lint static analysis have been extended to cover the CheckoutKitAndroidDemo sample app, in addition to the main library. This includes:

• Adding the detekt plugin and configuration to the sample app's build.gradle, using a new detekt.config.yml scoped to the sample
• Configuring Android Lint for the sample app with warningsAsErrors, dependency checking, and a lint.xml to suppress known false positives on branded vector assets
• Updating the CI workflow to set up the storefront environment before running lint, and running both lintRelease and detekt against the sample app
• Updating dev.yml commands (lint, format, check, detekt, android-lint) to also run against the sample app, with a check_storefront_env guard
• Applying detekt auto-corrections across the sample app source files (import ordering, line length, blank line cleanup, and formatting fixes)
• Replacing android.net.Uri.parse with androidx.core.net.toUri in AuthenticationHelper, moving the hero image to drawable-nodpi, removing unused launcher PNG assets, and removing unused string resources and imports

How to test

1. Run dev android lint and confirm it passes for both the library and the sample app
2. Run dev android check detekt and confirm detekt runs against both targets
3. Run dev android format and confirm auto-correct applies to both targets
4. Trigger the android-test CI workflow and confirm the new Sample static analysis and Android Lint step passes
