  Log Message:
  -----------
  NMS-20109: Make HA management an optional feature

- Create ha_instance_status from the coordinator at startup (advisory-lock
  serialized, includes agent_last_seen) instead of the core Liquibase
  changelog
- Write only last_heartbeat from the heartbeat cycle; state columns change
  on transitions only
- Add <mode>heartbeat-only</mode>: an external supervisor owns the state
  machine and OpenNMS only publishes liveness, never gating startup
- Move the HA REST endpoints out of opennms-webapp-rest into the ha-rest
  OSGi whiteboard bundle; enforce authorization via Spring Security
  intercept-urls
- Replace the filesystem-API config sync with a binary manifest transfer
  (sha256 diff, atomic apply, deletion propagation, sync-excludes); the
  hasync account no longer needs ROLE_FILESYSTEM_EDITOR
