* Update Android and iOS plugin configurations to remove deprecated parameters

- Upgraded Android SDK dependency to version 1.5.0-rc0.
- Refactored AppstackPlugin to eliminate `isDebug` and `endpointBaseUrl` parameters from the public `configure` API, now handled internally.
- Introduced a new method to read the development proxy URL from the app's manifest for local testing.
- Updated documentation to reflect the removal of deprecated parameters and their effects.
- Adjusted sample app and tests to align with the new configuration process.

* Enhance integration workflows for Appstack SDK logging and event delivery

- Added log capturing for Appstack SDK during iOS and Android integration tests to improve observability of event traffic.
- Updated iOS workflow to start capturing logs and display them after tests, ensuring visibility of SDK activity.
- Modified Android workflow to capture logcat output and surface relevant SDK logs in the test results.
- Adjusted integration tests to skip event delivery checks when the APPSTACK_API_KEY is not set, preventing false negatives in test results.

* Refactor Android integration test workflow to improve log capturing and event visibility

- Moved log capturing and test execution logic from the workflow file to a dedicated script (`ci_android_integration.sh`) to maintain shell state.
- Enhanced the script to capture logcat output and surface Appstack SDK logs in the CI job output, improving observability during integration tests.
- Updated the integration workflow to call the new script, streamlining the process and reducing complexity in the workflow configuration.
