chore(deps): update dependencies, bump parking_lot, rusqlite, gettext-rs

Refresh Cargo.lock to the newest compatible versions and move three
crates to their next minor release:

- parking_lot 0.12 -> 0.13
- rusqlite 0.40 -> 0.41 (newer bundled SQLite)
- gettext-rs 0.7 -> 0.8

gettext-rs 0.8 marks setlocale as unsafe; the three calls in i18n.rs
run before any thread starts, the same precondition the set_var calls
next to them already state.

rustc 1.99 deprecates AtomicX::fetch_update in favour of try_update
(stable since 1.95, below the 1.96 minimum), which failed
`clippy -D warnings` on main. Rename the two uses so clippy passes
without `-A deprecated`.

The open Dependabot alerts for zip (< 9.0.5) and rustls (< 0.23.46)
are already resolved on main by #69 (zip 9.2.0, rustls 0.23.46).
