chore(repo): bump mise rust to 1.95.0 to match rust-toolchain.toml

Completes the toolchain bump from #35665, which updated
rust-toolchain.toml to 1.95.0 but left mise.toml at 1.90.0.
CI installs rust via mise (sets RUSTUP_TOOLCHAIN, overriding
rust-toolchain.toml), so CI was still on 1.90.0 — failing the
sysinfo 0.39.1 MSRV check.
