rebase, make type read-only

Generally, the code itself looks good to me. But I have a general note regarding naming conventions.
I haven't seen all call sites yet (only the key generation diff is up) so I can't really tell but maybe it's worth revisiting the types and function arguments to have this as clean and consistent as possible.
In my diffs regarding AES encryption, I defined a few naming rules which I stick to (you can find them in this Notion doc). You can take inspiration from them.
If you think there's no point in doing this, just let me know ;)

| 5 ↗ | (On Diff #23697) | What about calling it EncryptedData? See my comment in decryptDatabaseFile |
| 7 ↗ | (On Diff #23697) | I'd call it ciphertext to be consistent, but up to you |
| 21 ↗ | (On Diff #23697) | Nit |
| 45–47 ↗ | (On Diff #23697) | How about connecting cipher and iv by using the EncryptionResult type you defined above (and perhaps renaming the type)? In GCM mode, they always need to be provided together anyways |

I updated the types to match those added in D7101.
Also, I added unit tests so you can check possible callsites: D7104

Oh, I didn't know those rules exist (btw. good job on those).

I think your suggestions make sense, thanks!
