## Description

In several places, our exception handling discards valuable debugging
context - either by losing the original stack trace or omitting metadata
from the underlying error. This makes diagnosing root causes
significantly harder.
This PR updates exception throwing to use [`raise ...
from`](https://docs.python.org/3/reference/simple_stmts.html#raise),
which:
1. The original stack trace is always preserved, even when wrapping
exceptions
2. Custom exceptions explicitly reference their underlying cause, making
error chains clearer

This commit introduces the preview functionality for the command. The preview displays a summary of what will be deleted before asking for user confirmation.
The feature is fully functional for the following flags:
- / : Correctly counts the number of data entries within the specified dataset.
- : Correctly counts the total number of datasets, data entries, and users in the system.
The logic for the flag is a work in progress. The current implementation uses a placeholder and needs a method to query a user directly by their ID to be completed.
