refactor: Remove access to shared container from SentryFileManager #6115
Description
Note
The pull request "refactor: Remove access to shared container from SentryFileManager" was created by @philprime but did not reference an issue. Therefore this issue was created for better visibility in external tools like Linear.
This pull request updates the initialization of the SentryFileManager class and its usage throughout the codebase to consistently require a dateProvider dependency, in addition to options and dispatchQueueWrapper. This change improves testability and dependency management by making the date provider explicit rather than relying on implicit or singleton-based injection. The update touches both production and test code, ensuring all usages of SentryFileManager are migrated to the new constructor signature.
