Track audit - Add missing user files events

Fixes #2640

This PR adds the following events:

• userFileEditShown
• userFileEditDismissed
• userFileEditSave
• userFileDeleteShown
• userFileDeleteDismissed

It also fixes a duplicated call to the event uploadedFilesHelpButtonTapped when tapping Add Files when the list was empty

To test

1. Start the app with a user with a subscription
2. Ensure that you have tracksLogging FF enable
3. Go to Profile Tab
4. Scroll down
5. Tap on Files
6. If you don't have any files you need to add them. If you are using the simulator the easiest way to add is to open Safary in a media file and then share it to PocketCasts
7. Tap on the file
8. Tap on the edit option and check if you see: userFileEditShown event on the console
9. Tap on cancel and check if you see: userFileEditDismissed event on the console
10. Tap on the edit gain option and check if you see: userFileEditShown event on the console
11. Now tap on Save and check if you see: userFileEditSave event on the console
12. Tap on the file again
13. Tap on delete and check if you see: userFileDeleteShown event on the console
14. Dismiss by dragging the sheet down and check if you see: userFileDeleteDismissed event on the console

Checklist

• I have considered if this change warrants user-facing release notes and have added them to CHANGELOG.md if necessary.
• I have considered adding unit tests for my changes.
• I have updated (or requested that someone edit) the spreadsheet to reflect any new or changed analytics.
