fix: skip grace-period text in close comment for IMMEDIATE_CLOSE_LOGINS

For PRs from IMMEDIATE_CLOSE_LOGINS (e.g. swiftwinds), evaluate_pr
returns 'close' immediately without ever posting a grace warning, so
the close comment should not reference a 1-day grace period.

Make close_pr take a grace_period_elapsed flag, default True, and
pass False from the main loop when the close path was the
immediate-close branch.
