fix(iam): resume site healing after leadership changes

Browse Source 
Keep one healing loop per process across replication configuration reloads. Reacquire leadership after a lease is canceled and allow shutdown while waiting, so temporary quorum loss cannot permanently stop revocation propagation.

## Healing, failures and operational cost
Each process starts one healing loop. Losing its distributed leadership lease
pauses work until leadership is reacquired; it does not permanently terminate
healing. Configuration reloads do not create extra loops. The 30-second interval
starts after leadership is acquired and after each completed pass. Initial lock
retries and endpoint recovery can add further delay; it is not a convergence SLA.
The normal IAM loaders maintain an in-memory index of deletion records and
retained boundaries, without secrets. Healing uses this index; it does not add a
second full walk of `config/iam/` every cycle. Existing full IAM loading still
