Introduce a new struct `WhisperUserSettings` to hold per-user
transcription settings. This allows users to customize Whisper
transcription for their specific needs directly in the `users.toml`
configuration file.
The changes include:
- Defining `WhisperUserSettings` with optional fields for `language`,
`hotwords`, and `initial_prompt`.
- Integrating `WhisperUserSettings` into the `User` struct, with
`#[serde(default)]` to ensure it defaults to
`WhisperUserSettings::default()` if not present in the TOML.
- Adding new unit tests to verify that users can be parsed correctly
with and without a `[user.whisper]` block.
- Updating existing tests in `auth_test.rs`, `upload_test.rs`, and
`web_test.rs` to include the new `whisper` field, ensuring backward
compatibility.
