Initialize Sentry in the background isolate.

Workmanager runs this callback in a separate isolate. Initialization in packages/uni_app/lib/main.dart does not initialize that isolate. (github.com)

Sentry starts with a no-op hub and queue. This transaction and the background exception captures therefore produce no reports. (raw.githubusercontent.com)

Initialize a Dart Sentry client before startTransaction. Share the DSN, sampling settings, and privacy filters with the main-isolate configuration.

line 21:
Initialize a Sentry client in the background callback before
`Sentry.startTransaction`; reuse the main-isolate configuration’s DSN, sampling
settings, and privacy filters so transactions and exception captures from this
isolate are reported.

Await the iOS tasks before marking the transaction successful.

Map.forEach does not await the futures returned by its asynchronous callback. (api.dart.dev) When a task suspends, this branch sets the success status and reaches transaction.finish() before the task completes. Later task errors cannot reach the new catch handler.

This remains incorrect after background Sentry initialization is fixed. Replace the asynchronous forEach with an awaited for loop before setting SpanStatus.ok().

Replace the asynchronous Map.forEach in the iOS task-processing branch with an
awaited for loop so every task completes and errors reach the catch handler
before setting transaction.status to SpanStatus.ok() and calling
transaction.finish().
