fix: enable rustls for imagod self-update GitHub client

[sizumita]

Motivation

• imagod self update failed to query GitHub releases in environments where TLS transport was unavailable for the imagod ureq configuration.
• This breaks update and tag-based update flows for users and increases operational risk.

Summary

• Enabled Rustls for imagod's HTTP client by updating crates/imagod/Cargo.toml: ureq = { workspace = true, features = ["rustls"] }.
• Kept other workspace dependency defaults unchanged.
• Updated Cargo.lock for the resulting dependency graph.

Validation

• cargo fmt --all
• cargo clippy --workspace --all-targets -- -D warnings
• cargo test --workspace
