Update TODOs for VaultTakeoverViewModel

Add placeholder TODO comments to the `VaultTakeoverViewModel` for future implementation work.

This commit clarifies upcoming tasks by:
- Adding a reference to a ticket (PM-28468) for fetching the organization name.
- Noting that the help link URL needs to be updated once it becomes available.
- Performing minor code formatting for better readability.
