Bump secrecy to 0.10

[clux]

Updates secrecy manually, replacing dependabot pr #1586 by removing now default hard features, and fixes to breaking changes.

changes noted from https://github.com/iqlusioninc/crates/blob/main/secrecy/CHANGELOG.md#0100-2024-09-17

SecretString internals is now a SecretBox, and this needs an .into() call to convert to a Box<S>.
See https://docs.rs/secrecy/0.10.2/secrecy/type.SecretString.html

This brings with it a small breaking change to the disk configuration format (since we export types containing the secrecy types).
