`MAX_SETTLEMENT_DELAY_LEDGER` enforced only in fee-based setters

[therealjhay]

Problemset_settlement_rule/set_default_rule enforce the delay cap, but the governance-sourced rule path (issue 24) bypasses it.

1. Delay cap bypass.
2. Divergent enforcement.
3. Test gap.

Solution

• Enforce the cap on the governance-derived rule conversion too.
• Test.

Acceptance Criteria

• Delay cap applies to all resolution paths.
• cargo test --workspace passes.

Note for Contributors: Write a clear PR description. Show the cap test.
