Expose rewards

Description

Callers can't read rewards state. This issue adds a read-only view.

Requirements and context

• Repository scope: StableRoute-Org/Stableroute-contracts only.
• Add a read-only view returning the current rewards state without mutating storage.
• Return a sane default before init.
• Cover values and pre-init default in tests.

Suggested execution

• Fork the repo and create a branch
• git checkout -b feature/rewards-91-view
• Implement changes
  • Write code in: the relevant module.
  • Write comprehensive tests in: cover the new behaviour and edge cases.
• Test and commit

Test and commit

• Run cargo fmt, cargo clippy --all-targets -- -D warnings, and cargo test.
• Cover edge cases: values after set, default before init.
• Include the full test output in the PR description.

Example commit message
